Suppressors — Why You Still Need Hearing Protection

OK, you’ve paid the tax stamp and acquired your new suppressor (aka “silencer” or “moderator”). Do you still need to wear earplugs or muffs? Absolutely. Even with that expensive new “can”, your rifle could be generating over 140 decibels (dB) of noise — about the same as as an unmuffled 9mm pistol shot. That’s loud enough to create permanent hearing loss with repeated exposure.

Firearms Are Loud: 140 dB to 175 dB

Audiology group ASHA explains: “Exposure to noise greater than 140 dB can permanently damage hearing. Almost all firearms create noise that is over the 140-dB level. A small .22-caliber rifle can produce noise around 140 dB, while big-bore rifles and pistols can produce sound over 175 dB. Firing guns in a place where sounds can reverberate, or bounce off walls and other structures, can make noises louder and increase the risk of hearing loss. Also, adding muzzle brakes or other modifications can make the firearm louder. People who do not wear hearing protection while shooting can suffer a severe hearing loss with as little as one shot[.] Audiologists see this often, especially during hunting season when hunters and bystanders may be exposed to rapid fire from big-bore rifles, shotguns, or pistols.” Source: ASHA, Recreational Firearm Noise Exposure.

Suppressors, On Average, Reduce Noise Levels about 30 Decibels
In an article for Ammoland, gunwriter Sam Hoober says that you can expect about 30 decibels (dB) of noise reduction from the average suppressor: “Looking at a few different products, SilencerCo attests their suppressors reduce the sound pressure of a 9mm gunshot to anywhere from 125.7 dB to 131.5 dB, depending on the model. Advanced Armament Co, another popular supplier, attests a 23 dB to 33 dB reduction or down to 127 dB. Liberty Suppressors, another manufacturer, attests a reduction of 24 dB to 38 dB, depending on model and other factors. In short, we can presume something on the order of 30 dB of attenuation as an average.”

Using that 30 dB number you can quickly discern that you’ll still need hearing protection — good hearing protection — when shooting any suppressed firearm (even a .22 LR). “Spikes of 130 dB and more can result in permanent hearing damage instantly”. Source: NRA Blog.

The Myth of the “Quiet” .22 LR
The NRA Blog notes that “many rimfire shooters, particularly those using the beloved .22 Long Rifle cartridge, argue that the small .22 LR caliber doesn’t produce enough sound to damage your hearing”. So, is that really true. or is it a myth?

In fact, a .22 LR can be much louder than you think — a .22 LR pistol can produce sound levels of 134 dB. That’s well above the normal human pain threshhold.

Sound Levels for Common Noises:

9mm Luger pistol: 160 dB

Jet aircraft engine (near): 140 dB

.22 LR pistol: 134 dB

Normal human pain threshold: 120 dB

Noisy Nightclub: 110 db

Riding Motorcycle at 65 mph: 103 db

Power Lawnmower: 95 dB

Hearing damage possible: 85 dB (sustained for 8+ hours)

Ringing Telephone: 80 dB

Normal conversation: 60 dB


The Risk of Hearing Loss
Hearing loss can be progressive and irreversible. If you are a shooter, this is serious business. As the NRA Blog cautions: “You may not even realize you’re harming your hearing. Hearing loss occurs gradually, and can go effectively unnoticed until symptoms become severe. By then, the damage is done.”

Nobody wants to go deaf. But we often see shooters without effective hearing protection when they are walking around a few yards behind the firing line. That’s bad — even if you are away from the firing line, gunshot noises can damage your hearing. You MUST use effective hearing protection every time you go to the range. Good foam earplugs costs mere pennies but they can prevent deafness in your later years. Many folks also wear muffs over plugs.

NSSF Hosts Suppressor Demonstration for News Media

NSSF Suppressor News Media Demonstration demo Manassas Class III Regulation

Last month, the National Shooting Sports Foundation (NSSF) hosted a suppressor demonstration at Elite Shooting Sports in Manassas, Virginia. Sig Sauer and Daniel Defense suppressor experts were presenters. Olin Corporation supplied ammunition.

The Daniel Defense representative noted that suppressors do not render a firearm silent (despite what Hollywood movies might show). The sound level of an un-suppressed AR15 firing is 165-175 dB. With a suppressor in place, the sound level for the same 5.56 rifle drops to around 135-140 dB. That is a significant noise reduction, but the rifle is still producing a noise louder than a jack-hammer (and hearing protection is still recommended). Watch the video below to learn other important facts about firearm suppressors.

NSSF Hosts Suppressor Demonstration for News Media

The objective of the NSSF demo was to give the news media more accurate information about hearing protection devices. In addition, the NSSF wanted to correct many popular misconceptions about suppressors. Mainstream media reports about sound suppressors are typically inaccurate, incomplete, and misinformed. For example, most media stories fail to acknowledge that suppressors are legal throughout Europe, and widely used by European hunters and target shooters. If you were to believe the typical news report on suppressors, silencers are evil and dangerous. The NSSF demo was designed to replace ignorance with facts.

300 Blackout Basics — Specs and Cartridge INFO

300 BLK AAC Blackout

As the .30-Cal cartridge of choice for the AR15 platform, the 300 AAC Blackout, also known as 300 BLK, has become quite popular with black rifle owners. You can now purchase quality factory ammo and even premium Lapua 300 BLK brass. Some folks wonder — “why consider a 300 BLK”? Here are the key reasons you may want to acquire a 300 AAC Blackout upper for your AR:

FIVE REASONS to Shoot the 300 BLK:

1. Easy Conversion: Use your current AR lower, bolt/carrier, buffer, and magazine. The only part you need to change is the barrel.
2. Hunting Capability: 300 BLK conforms to state hunting regulations which may require a cartridge larger than .22 caliber. The 300 BLK shoots .308 caliber bullets.
3. Suppressor-Friendly: You can shoot heavier bullets subsonic. The subsonic capabilities of the 300 BLK make it ideal for use with a suppressed AR.
4. Great Barrel Life: With a .30-caliber bore and a modest powder charge, barrel life is outstanding.
5. Great Brass: No Case forming is required — just buy Lapua 300 BLK brass.

The 300 AAC Blackout was created by Advanced Armament Corp. and Remington primarily for the military as a way to shoot .30-caliber bullets from the M4/AR15 platform while using standard magazines. As explained by Robert Silvers, AAC’s R&D Director: “[You can] shoot 30 caliber from your AR while still using normal magazines with full capacity. Even the bolt stays the same, and all that changes is the barrel.” CLICK HERE for more information.

300 BLK AAC Blackout magazine

The concept of putting a .30-caliber bullet in a shortened 223 case has been done before, but not as an industry-wide standard that anyone can make products for, royalty-free. SAAMI, the industry standards organization, adopted and standardized the AAC 300 Blackout earlier this year. The SAAMI diagram for the 300 BLK is shown below.

300 AAC Blackout SAAMI Diagram
300 Blackout SAAMI Cartridge Specification

Affordable Factory 300 BLK Ammo is Available
Remington now sells a variety of 300 BLK ammo: 1) 125 grain open-tip match with a custom Sierra bullet; 2) 220gr subsonic, and 3) 125gr AccuTip (photo below). While the 300 BLK is easy (and inexpensive) to reload, Remington and AAC recognized that most people are not reloaders. So Remington will be budget-priced UMC-brand 300 BLK ammo through at just $12.99 per box — that’s less than most other rifle cartridges than are more powerful than the .223.

300 AAC BLK ammo

The 300 AAC Blackout definitely works for hunters who want to use their AR15-platform rifle. And it also serves as a specialized 30-Cal “rule-beater” that lets 3-Gun competitors “make major” with a low-recoil cartridge that also offers long barrel life. For those who need to run a .30-caliber cartridge from a standard AR15 platform (as opposed to the AR10), the 300 AAC Blackout makes sense. But for hunters using a bolt gun, there are any number of tried and true options, such as the 7.62×39, .30-30, and, of course, the .308 Winchester (7.62×51 NATO).

WARNING: With some bullet options (and setback during chambering) 300 Blackout rounds will go into a .223 chamber and fire. Putting a .308-caliber bullet in a .224-diameter barrel is a recipe for disaster. You can blow up your gun and sustain serious injury. That’s why we recommend you have a dedicated 300 BLK upper and mark your magazines. Also, always, always check your .223 magazines to ensure no 300 BLK rounds worked their way in when you loaded the mags. There have been a number of Kabooms recorded from 300 BLK rounds fired in a .223 Rem/5.56×45 chamber. CLICK HERE to see actual 300 BLK in .223 Rem chamber.

President’s Son Supports New Suppressor Legislation in Congress

Hearing Safety act suppressor silencerco thunder beast silencer legislation
Thunder Beast Arms suppressors are popular with tactical competitors and hunters.

Hopefully, in the near future, it will be much easier to purchase a suppressor for your firearm. Legislative efforts to reform the laws governing suppressors are moving forward in the U.S. Congress.

On January 9, 2017, Congressman Jeff Duncan (R-SC), co-chair of the Congressional Sportsmen’s Caucus (CSC), introduced H.R. 367 to remove suppressors from National Firearms Act control and treat them the same as long guns, replacing the outdated federal transfer process with a NICS background check. The measure picked up 42 Republican co-sponsors and one Democrat co-sponsor. Sen. Mike Crapo (R-Idaho) introducted the similar Hearing Protection Act of 2017 (S. 59) in the U.S. Senate.

The new silencer reform legislation has a key backer — Donald Trump, Jr., the President’s son. “It’s about safety. It’s a health issue, frankly.” Trump Jr. explains in a video interview with Joshua Waldron, the founder of SilencerCo.

Donald Trump Jr. Talks about Suppressors and Shooting Safety

Donald Trump Jr. Talks about Suppressors
“I’ve had the privilege of being able to hunt in Europe, where some of the strictest gun laws in the world exist. Guess what… virtually every hunting gun there is suppressed. It’s about safety. If you had that kind of noise levels in any other industry as you would in shooting sports, OSHA would be all over the place. It’s about safety.” Trump Jr. said the current U.S. suppressor laws are “arbitrary policies by people who don’t know what they’re talking about.” He says it’s time the U.S. follow the lead of European nations, and adopt sensible suppressor policies, “because if Europe can do it, American better well be able to do it.”

NSSF Supports Hearing Safety Act
The National Shooting Sports Foundation (NSSF) supports efforts to make silencers/suppressors easier to purchase. “This legislation will enable gun owners to have better access to hearing protection products and improve safety for the shooting sports by removing extensive wait times for burdensome paperwork processing that does not advance public safety,” said Lawrence Keane, NSSF senior VP and general counsel.

“Anyone who has ever worried about hearing loss from shooting might want to lend their ears to this cause” said Emily Taylor, an attorney at the Houston law firm of Walker & Byington.

Current law imposes signficant barriers to suppressor ownership, Taylor explained: “Currently, the manufacture, purchase, and possession of firearm silencers are regulated by the ATF and must comply with the requirements laid out in the National Firearms Act (NFA). Anyone who wants a firearm suppressor must first get approval from the ATF and pay the required tax. An extended waiting period comes along with the time it takes the ATF to process these requests.”

“The Hearing Protection Act seeks to amend the law so that firearm silencers are treated the same way as long guns,” Taylor added. “The bill would make it so that there is no longer a tax associated with the transfer of a firearm silencer, and anyone who pays a tax on a silencer after October 22, 2015 could receive a refund of such tax. Lastly, the bill would preempt certain state laws that tried to impose taxes or registration requirements on firearm silencers.”

In this excellent video from SilencerCo.com, NFL Pro Bowl Tackle Fletcher Cox works with LG Outfitters to stalk and harvest Nilgai Antelope using a suppressed rifle. “Nilgai are pretty special animals — they’re from India. Originally brought down by the King Ranch in the 1930s, they’ve just gone nomadic and they’re all over South Texas.” — Leeroy Gonzales, LG Outfitters.

“Hunting goes back to the way you approach things. You’ve gotta have a game plan.”

As all committed hunters know, the majority of the hunt is in the preparation. Selecting your gear, choosing the perfect location, waking up before dawn, posting up to patiently wait…

Fletcher Cox is all too familiar with putting time and effort into perfecting his craft and honing the execution. As a Pro Bowl defensive tackle for the Philadelphia Eagles, Cox knows that dedication and practice make for the best possible outcome.

Fletcher Cox confirms his Zero before the hunt.

ATF White Paper Recommends Changes in Suppressor Laws

ATF silencer suppressor white paper

In the near future, there could be changes in the way the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) treats sound suppressors (aka “moderators” or “silencers”). An official government White Paper, dated 1/20/17, was recently leaked to the press and revealed by the Washington Post.

CLICK HERE to READ FULL Text of ATF WHITE PAPER

ATF silencer suppressor white paper

The ATF White Paper makes some key points about suppressors:

1. 42 States currently allow silencers.
2. Silencers are not a threat to public safety, and are rarely used in criminal activities.
3. The inclusion of suppressors in the NFA is “archaic” and should be reevaluated.
4. The definition of regulated suppressor components should be narrowed, so that only key items are regulated as opposed to “any combination of [silencer] parts”.
5. A change in Federal law removing silencers from regulation under the NFA would save resources, allowing the ATF to focus on reducing actual gun-related crime.

ATF silencer suppressor white paper

Here is the operative text of the ATF White Paper:

Current Federal law requires ATF to regulate silencers under the NFA. This requires a Federal tax payment of $200 for transfers, ATF approval, and entry of the silencer into a national NFA database. In the past several years, opinions about silencers have changed across the United States. Their use to reduce noise at shooting ranges and applications within the sporting and hunting industry are now well recognized.

At present, 42 states generally allow silencers to be used for sporting purposes. The wide acceptance of silencers and corresponding changes in state laws have created substantial demand across the country. This surge in demand has caused ATF to have a significant backlog on silencer applications. ATF’s processing time is now approximately 8 months. ATF has devoted substantial resources in attempts to reduce processing times, spending over $1 million annually in overtime and temporary duty expenses, and dedicating over 33 additional full-time and contract positions since 2011 to support NFA processing. Despite these efforts, NFA processing times are widely viewed by applicants and the industry as far too long, resulting in numerous complaints to Congress. Since silencers account for the vast majority of NFA applications, the most direct way to reduce processing times is to reduce the number of silencer applications. In light of the expanding demand and acceptance of silencers, however, that volume is unlikely to diminish unless they are removed from the NFA. While DOJ and ATF have historically not supported removal of items from the NFA, the change in public acceptance of silencers arguably indicates that the reason for their inclusion in the NFA is archaic and historical reluctance to removing them from the NFA should be reevaluated.

ATF’s experience with the criminal use of silencers also supports reassessing their inclusion in the NFA. On average in the past 10 years, ATF has only recommended 44 defendants a year for prosecution on silencer-related violations; of those, only approximately 6 of the defendants had prior felony convictions. Moreover, consistent with this low number of prosecution referrals, silencers are very rarely used in criminal shootings. Given the lack of criminality associated with silencers, it is reasonable to conclude that they should not be viewed as a threat to public safety necessitating NFA classification, and should be considered for reclassification under the [Gun Control Act] (GCA].

If such a change were to be considered, a revision in the definition of a silencer would be important. The current definition of a silencer extends to “any combination of [silencer] parts”, as well as “any part intended only for use in” a silencer. Compared to the definition of a firearm, which specifies the frame or receiver is the key regulated part, any individual silencer part is generally regulated just as if it were a completed silencer. Revising the definition could eliminate many of the current issues encountered by silencer manufacturers and their parts suppliers. Specifically, clarifying when a part or combination of parts meets a minimum threshold requiring serialization would be useful.

Hearing Protection Act (H.R. 367) Introduced in Congress

hearing protection act Congress Duncan Carter

We may see a big change in how sound suppressors are regulated in the future, if new legislation from the Congressional Sportsmen’s Caucus (CSC) becomes law. On January 10, 2017, Rep. Jeff Duncan (SC) and Rep. John “Judge” Carter (TX) introduced H.R. 367, the Hearing Protection Act (HPA). This law would remove suppressors (aka “moderators”) from National Firearms Act (NFA) control, eliminating requirements of extensive paperwork, and purchase of a tax stamp. If the Hearing Protection Act becomes law, suppressors could be purchased through an FFL (after a NICS background check), just like a normal, non-NFA firearm. This would make suppressors more affordable in the 42 states where suppressors are legal to own. What’s more, the new legislation includes a provision to refund the $200 transfer tax to applicants who purchased a suppressor after Oct. 22, 2015.

Suppressors function by trapping the expanding gasses at the muzzle, allowing them to slowly cool in a baffled chamber. On average, suppressors reduce the noise of a gunshot by 20-35 decibels (dB), roughly the same sound reduction as earplugs or earmuffs. In addition to hearing protection, suppressors also mitigate noise complaints from those who live near shooting ranges.

“Many gun owners and sportsmen suffer severe hearing loss after years of shooting, and yet the tool necessary to reduce such loss is onerously regulated and taxed. It doesn’t make any sense,” said Chris W. Cox, executive director, NRA-ILA. “The Duncan-Carter Hearing Protection Act would allow people easier access to suppressors, which would help them to better protect their hearing.”

Guns.com explained how the Hearing Protection Act will change current law: “Since 1934, the federal government has treated devices designed to muffle or suppress the report of firearms as Title II devices that required registration under the National Firearms Registration and Transfer Record and mandated transfers that included a $200 tax stamp. The Duncan-Carter bill would repeal this requirement and treat suppressors as firearms — which would allow them to be transferred through any regular federal firearms license holders to anyone not prohibited from possessing them after the buyer passes an FBI instant background check.”

This video discusses an earlier version of the Hearing Protection Act, H.R. 3799:

“For the past five years, the Congressional Sportsmen’s Foundation (CSF) has worked alongside the state legislative sportsmen’s caucuses in the National Assembly of Sportsmen’s Caucuses, the American Suppressor Association, and many other partners at the state level to normalize the use of suppressors throughout the nation,” said CSF President Jeff Crane. A similar bill was introduced last year by Rep. Matt Salmon (AZ) but that legislation never made it out of committee.

If you have purchased a suppressor in the last year, the HPA could put money back in your pocket. As drafted, the HPA also includes a provision to refund the $200 transfer tax to applicants who purchased a suppressor after October 22, 2015.

CANtastic — Learn About Suppressors on GunTalk

Sound Suppressor

This Sunday, December 4, 2016, Tom Gresham’s GunTalk Radio will feature a discussion of suppressors, aka “silencers”, “cans”, or “sound moderators”. With firearms industry experts, Tom will discuss the current regulations for suppressors, as well as efforts to remove silencers from the list of NFA items requiring expensive tax stamps and cumbersome paperwork. With the Republican gains in the November election, there are renewed calls for changes in the laws regulating suppressors. In fact, many suppressor advocates say now is the time for sound moderators to be removed from NFA control altogether, so that suppressors could purchased “over the counter” just like scopes, slings, or other common shooting/hunting accessories.

How Suppressors Work — The Science of Silencers

Suppressors are a valuable accessory for general-purpose rifles, so we would like to see suppressors legal in all 50 states. In addition, we believe the USA should follow the lead of European nations which promote the use of sound suppressors for safety reasons. In most European countries, for example, you can purchase a suppressor easily. There are no difficult barriers to ownership, onerous background checks, or special taxes. The Europeans seem to understand that suppressors protect the hearing of shooters (and bystanders), while suppressor use also dramatically reduces “noise pollution” concerns for shooting ranges in urban/suburban areas. The Europeans also understand that sporting/hunting use of suppressors does NOT increase criminal or gang activity. It is time for the USA to adopt these more enlightened viewpoints.

TECH TIP: Optimizing Muzzle Brake Accuracy and Effectiveness

muzzle brake test tuner Ray Bertalotto

Muzzle brakes are controversial. Some people swear by them, while others swear at them. Still, there’s no question that a good brake can reduce felt recoil up to 45%. And likewise, the best brakes, when installed properly, seem to have no negative effect on accuracy.

Roy Bertalotto has done considerable experimentation with muzzle brakes, testing dozens of brake designs on his own rifles over the past few years. Roy’s article, Adventures with Muzzle Brakes, discusses various aspects of muzzle brake design and performance. Roy doesn’t claim that his testing is definitive, but his article is definitely worth a read. Here are some of Roy’s interesting findings:

Exit Hole Diameter
“Best accuracy and effectiveness of the brake was obtained with a hole .020″ over bullet diameter. If the exit hole is too small, such as +.005″ over bullet diameter, accuracy suffers. If the depth of the exit hole is too shallow, the metal around the hole will erode very quickly.”

Hole Placement
“The most effective braking was with a brake 1″ in diameter with a 3/4″ exit hole on each side, just in front of the muzzle. The bullet passes through a cone of 35 degrees before it exits the brake. (Like the tank example), Incredible reduction of recoil. But loud and ugly. Very easy to make since you don’t need a spin fixture or a dividing head.”

Bottom Gas Venting Helps Accuracy
“In my tests, not having holes all around the brake effects accuracy a bit. I believe it does something to the bullet by the air pushed ahead of the bullet creating unequal turbulence in the bullet path. I’ve tried a few brakes where I drilled only holes on the top, test fired, and then completed holes on the bottom and in every case, accuracy improved.” Below are spiral-ported brakes crafted by Clay Spencer.

Brakes Work Best with High-Pressure Cartridges
“The higher the pressure of the particular round, the more effective the brake. I have over 20 rifles with brakes. The 220 Swift is the king of reduction. Followed very closely by the 25-06, 6mm Remington, any Weatherby small bore. With a proper brake and a hot handload under a 40 gr bullet, the Swift will move 1/2″ to the rear and 0 muzzle rise! Big boomers with low pressure like 45-70s and shot guns benefit the least.” [Editor’s Note: Roy is judging effectiveness by the percentage of recoil reduction rather than absolute levels of recoil. Obviously if you start with a heavier-recoiling round, the absolute amount of recoil energy reduction is greater. Roy is really talking about efficiency–brakes are most efficient when used with high-pressure cartridges.]

Installation is Key to Accuracy
Roy’s findings are fascinating and suggest that further study of muzzle brakes is warranted. But we can all agree that precision installation of the brake is essential for accuracy. A poorly-installed, mis-aligned brake will degrade accuracy, that is well-known.

Harrell’s Precision has made thousands of muzzle brakes, in many styles and port arrangements. The Harrell brothers offer some good advice for gunsmiths installing brakes: “Muzzle brakes aren’t magic, they reduce recoil by redirecting exiting gas. What’s important is that they are straight and the threads are perpendicular with the base. The only way to get the base and threads perpendicular is to thread, not tap, them on a lathe.”

Dope for Your Scope — Handy Laminated Ballistics Card

JBM laminated ballistics card zak smith

Tactical ace Zak Smith of Thunder Beast Arms employs a simple, handy means to store his elevation and wind dift data — a laminated data card. To make one, first generate a come-up table, using one of the free online ballistics programs such as JBM Ballistics. You can also put the information in an Excel spreadsheet or MS Word table and print it out. You want to keep it pretty small.

Above is a sample of a data card. For each distance, the card includes drop in inches, drop in MOA, drop in mils. It also shows drift for a 10-mph cross wind, expressed three ways–inches, MOA, and mils. Zak explained that “to save space… I printed data every 50 yards. For an actual data-card, I recommend printing data every 20 or 25 yards.” But Zak also advised that you’ll want to customize the card format to keep things simple: “The sample card has multiple sets of data to be more universal. But if you make your own data card, you can reduce the chance of a mistake by keeping it simple. Because I use scopes with MILS, my own card (photo below left) just has three items: range, wind, drop in MILS only.”

Once you have the card you can fold it in half and then have it laminated at a local office store or Kinko’s. You can keep this in your pocket, tape it to your stock, or tie the laminated card to your rifle. If you regularly shoot at both low and high elevations, you may want to create multiple cards (since your ballistics change with altitude). To learn more about ballistic tables and data cards, check out the excellent Practical Long-Range Rifle Shooting–Part 1 article on Zak’s website. This article offers many other insights as well–including valuable tips on caliber and rifle selection.

ballistics data scope coverScope-Cover Mounted Ballistics Table
Another option is to place your ballistics card on the back of the front flip-up scope cover. This set-up is used by Forum member Greg C. (aka “Rem40X”). With your ‘come-up’ table on the flip-up cover you can check your windage and elevation drops easily without having to move out of shooting position.

Greg tells us: “Placing my trajectory table on the front scope cover has worked well for me for a couple of years and thought I’d share. It’s in plain view and not under my armpit. And the table is far enough away that my aging eyes can read it easily. To apply, just use clear tape on the front objective cover.”

SilencerCo Leads Huge Growth in USA Suppressor Market

Suppressor Silencer Josh Waldron Dean Weingarten Silencerco

In this article, Gun Watch Editor Dean Weingarten interviews SilencerCo Founder/CEO Josh Waldron. Started in 2008, SilencerCo is an amazing success story. The company now sells 18,000 silencers a month. To put that in perspective, a decade ago, the entire domestic suppressor industry was selling 18,000 suppressors a YEAR. SilencerCo now controls 65% of the suppressor market in the USA, and its business is growing 100% a year.

This growth is remarkable considering that suppressors remain highly regulated and costly to acquire. The National Firearms Act (NFA), passed in 1934, imposes significant restrictions and requires a $200 tax to be paid on each silencer sold.

How Suppressors Work — The Science of Silencers

Interview with Josh Waldron, CEO of SilencerCo
©2016 by Dean Weingarten: Permission to share is granted when this notice is included.

At the NRA Annual Meeting in Louisville, Kentucky, I was able to talk to Josh Waldron, CEO of SilencerCo. Josh is more than a visionary. He is a man who acted on his vision, and is changing the gun culture and the national culture.

I [visited] the SilencerCo booth during the NRA Annual Meeting. I was told that SilencerCo produces about 65% of the silencers in the United States. The company is growing so fast that it was hard to keep up with the number of employees, currently about 330 and rising quickly. There is no doubt that SilencerCo holds a dominant market share and is growing at an exceptionally fast rate. I asked Josh about the future of silencers and silencer legislation.

Q: Do you have a plan, and can you tell me about it?

“It starts as education. Ever since we started the company in 2008, we have had a focus on education and advocacy. When I first started the company… only 18,000 silencers were sold in the United States each year, and that was every manufacturer.”

“From the time we have started until now, there were 18,000 then, we are now selling about 18,000 silencers every month, just SilencerCo.”

“In the last five years, this has been the fastest growing segment of the firearms industry.”

Suppressor Silencer Josh Waldron Dean Weingarten Silencerco

When I first started the company… only 18,000 silencers were sold in the United States each YEAR [from] every manufacturer. We are now selling about 18,000 silencers every MONTH, just SilencerCo. — Josh Waldron

“People are just starting to understand. This is not a ‘cool accessory’ as much as it is a personal protection/personal safety device, just as you would consider any other device that keeps you safe while you shoot, such as safety glasses. It is really the only true way to hunt while you protect your hearing. As we continue to educate the market, it grows exponentially. A guy will get one who has never had one before, he brings it home, he shows his friends, and they say ‘Oh my gosh, I want to buy one!’ Every time we get suppressors out there, the snowball continues to grow and get bigger and bigger.”

Q: Your market share is dominant. Your sales growth is exponential, isn’t it?

“Yes … pretty amazing. We are growing 100% every year.”

WATCH X-Ray View of Shots Through Silencer (28,000 frames per second, 22 Sparrow)

Q: Do you fear that removal of suppressors from the NFA (National Firearms Act) will cut into your profit margin?

“I don’t think so. We don’t get to take full benefit of the economies of scale. We have to order materials on a small-batch basis. As we increase the number of suppressors going out the door we decrease the amount that it costs us. We haven’t pushed it to the level where are seeing those economies of scale.”

“We are always going to be a top-shelf brand. We are never going to discount our brand. We will be a leader in the industry, continually. I do believe there will be a lot of new entrants to the industry. I do not think that will hurt our brand or hurt our market.”

Q: I saw the Maxim 9, SilencerCo’s integrally-suppressed pistol, at the SHOT Show in Las Vegas. Is the Maxim 9 in production yet?

“It is not in production yet. Projects of this size take a lot of research and development. They take a lot of torture testing. We have to put it through a lot of standard testing. We use outside firms that come in and test and evaluate, so that we can hold our heads up high and say ‘This is a duty grade weapon’. We are not going to release it until it is.”

“I do not want to be marketing to our men and women in uniform, and saying this is a safe way to shoot until we can say this is a perfect firearm for them. The amount of testing is extremely rigorous. We are on schedule. We will release it, probably in December.”

Q: Is the Maxim 9 your entry into a future market of integrally-suppressed firearms?

“Yes. Our intention with the Maxim brand is to have integrally-suppressed firearms in that brand. We are talking everything from shotguns to rifles to pistols. The pistol is a good place to start because it is the holy grail of integrally suppressed guns that everyone has wanted. It is extremely difficult to do. People have tried it and failed, years and years, for decades, and this is the first time it has actually been viable and real. We are very excited about that, and very proud of that. We are going to move into new calibers as soon as this one starts shipping. We are very excited to expand that line.”

Suppressor Silencer Josh Waldron Dean Weingarten Silencerco

“Do I think the gun companies will compete? They can try. Number one, our IQ is amazing around this product. We spent a lot of time researching every firearm, every handgun that you can think of. How the mechanisms worked, and why. We had to be thorough. Which is why we designed the gun from the ground up. We went into every single style of this type of firearm, and other types of handguns as well, and really, truly understand how it needed to be designed. We had to take every mechanism, the guide rods, the springs, the things that are in front of the chamber in a conventional handgun, and move them behind the chamber. That was our biggest challenge. Do I think that some of those guys will start competing and get around our IQ? It will be a lot harder for them than for us. Because we are the ones who figured it out in the first place, and we have a lot of patents around that.”

Q: Rifles have had a lot of [suppressor] solutions … for a long time.

“We will get into those lines, the rifle lines. The difference is that we will design the gun, just the same way as we did for the Maxim 9. We will design the gun for the suppressor instead of putting on a suppressor designed for the gun, so our guns will be better.”

Suppressor Silencer Josh Waldron Dean Weingarten Silencerco

“There are about 400 million firearms in the U.S. right now. Most of those were not designed with a suppressor in mind. There is a huge market for retrofitted suppressors.”

“Which is what we have been doing for the last eight years, it is what we have done as a company which is providing solutions for firearms that already exist. The field is ready to harvest as far as creating a new platform. A new platform that has never been done before this, that was designed from the ground up with the intention of being suppressed, integrally suppressed.”

Q: You say you are going to stay on the high end. I looked at some of the markets. There is a lot of low end potential out there.

“There is. It is something that I am just not interested in. Number one, I do not know how to make something that is not the best.”

“It is impossible to know what the percentage of the market the high end will be. It is important to me to make the best product in the world. I am a brand guy. My brand is very important to me to so if I am making things that are less than the best, that is not ever something that I want. I always want to be top shelf.”

Q: Are you exporting much?

“We export, yes. We can’t export to the commercial market. Only to the military and law enforcement. It is a State Department thing.

“We have a bill right now, it is called the Suppressor Export Act. Congressman Jeff Stewart is the one that is sponsoring that bill for us. It would ensure that the State Department would have to allow us to take part in the world market, that is available, that we are not able to take part in right now. We can only export to law enforcement and military, but not to the commercial market. But with this bill, we would be able to export to everybody. If there is a country where it is legal to have suppressors, we would be allowed to export to them.”

“There are suppressor manufacturers all over the world, and they sell all over the world. The United States is the only place where they are this regulated. It is just crazy. You can go to the UK, where it is really hard to own a gun, and you can buy a suppressor over the counter, without a background check.”

“We are behind the curve when it comes to the rest of the world.”

Q: Can [one buy stock in Silencerco]?

“We are a private company.”

Michigan Approves Use of Suppressors for Hunting

suppressor hunting Michigan

Here’s good news for suppressor owners in the Great Lakes state. The Michigan legislature has approved the use of suppressors for hunting. On February 11th, Michigan became the 38th state to allow for the use of firearm suppressors while hunting when the Natural Resources Commission (NRC) voted 4 – 1 to approve an amended version of Wildlife Conservation Order Amendment No. 1 of 2016. The measure became effective immediately.

The American Suppressor Association led a coalition working to legalize suppressor hunting in Michigan. Other organizations involved were the National Rifle Association (NRA), the Congressional Sportsmen’s Foundation (CSF), Michigan United Conservation Clubs (MUCC), and Safari Club International (SCI).

“We are incredibly excited that hunters in the great state of Michigan can now use suppressors to help protect their hearing while they’re in the field,” said Knox Williams, President of the American Suppressor Association. “It was a pleasure working to educate the NRC Commissioners and members of the DNR on the realities of suppressor use. We applaud their decision to remove the prohibition on suppressor hunting without the two restrictive provisions. In doing so, they have done their part to ensure that the next generation of hunters does not have to sacrifice their hearing.”

Our friend Paul Phillips (above), is pleased with this change: “With this new Law that passed in Michigan Today, I will be hunting with my GEMTECH arrow silencer. I can’t wait for Spring to start Shooting ELR.”

Major Increase in Sales of Suppressors and other NFA Items

Suppressor, Class III, ATF, tax stamp, maxim, silencerThis X-ray photograph reveals a variety of suppressor baffle configurations:

Report by NSSF
Apparently, today’s shooters like the sounds of silence. Americans are buying and licensing more suppressors and other NFA (National Firearms Act) items than ever before. The number of NFA applications filed with the NFA Branch at ATF continues to rise. With a greatly increased staff of 25 Legal Instrument Examiners, the backlog of NFA forms has been whittled down from more than 80,000 to about 36,000. Much of the intense increase in interest in NFA items is focused on silencers. According to ATF’s 2011 Commerce in Firearms Report, as of December 2010 there were 284,087 lawfully registered silencers in the United States. As of March 2014, there were 571,750. That’s means the number of registered suppressor more than doubled in three and a quarter years. And 2015 will probably be a record year for suppressor sales.

A Brief History of Suppressors (aka “Silencers”)
Hiram Percy Maxim, the son of Hiram Stevens Maxim (inventor of the Maxim machine gun) created the first firearm sound suppressors. An early advertisement for his Maxim Silencer Company explained that the hot propellant gases from discharging the firearm “are made to whirl around inside the Silencer,” and cannot leave the silencer until they have slowed down enough to not produce a loud noise. Initially, silencers were inexpensive and easy to obtain. Before the adoption of the National Firearms Act in 1934, Mr. Maxim sold a variety of silencer designs priced from $5.00 to $9.50. These were shipped in the U.S. Mail, without restrictions. Things are much different today — to own a suppressor, one must obtain federal approval and pay a special tax.

silencer, suppressor, maxim, NFA, Firearsm Act

Silencers consist of a few basic parts. The CTD Shooter’s Log explains: “The envelope is the cylindrical metal tube in which the other components are stuffed. Inside the envelope are the expansion chamber and baffles. The expansion chamber is a relatively big empty space surrounding the muzzle, and the baffles are like coffee cups stacked on top of each other with a hole drilled through the middle of them for the bullet to pass through. This is where most of the ‘magic’ happens within the silencer.”

Ruger Unveils 10/22 Takedown with Threaded Target Barrel

Ruger 10/22 takedown target bull barrel suppressor

Ruger has been on a roll lately. The Ruger Precision Rifle has been a big hit, selling out at dealers across the country. Now Ruger has unveiled its new “tactical blacK” take-down version of the 10/22 with a suppressor-ready threaded bull barrel and modular stock. Ruger has offered 10/22 take-downs before but those previous models all had relatively skinny barrels. This version is more macho, and we expect it will be very popular. It’s just the thing for tactical rimfire games. The ability of the threaded barrel to take a suppressor will be attractive to potential buyers. A suppressed .22 LR is a very, very quiet tool.

Ruger 10/22 takedown target bull barrel suppressor

This new Ruger 10/22 Takedown with Target Barrel features a hammer-forged .920″-diameter, 16.10″-long, fluted “target” barrel. The muzzle is threaded ½”-28 and fitted with a thread cap. Those threads ain’t just for a muzzle brake — Ruger knows buyers will be attaching suppressors. This new target barrel takedown model also incorporates the Ruger Modular Stock System which offers interchangeable low and high comb modules.

Ruger 10/22 takedown target bull barrel suppressor

The Ruger 10/22 Takedown with Target Barrel is lightweight and compact. Weight (before optics) is just 5.5 pounds. Total length, assembled, is 34.6 inches, but each sub-assembly is under 20.25 inches. The two sections (barrel assembly and action/buttstock assembly) fit in a convenient black nylon carrying case, which provides ample storage with extra pockets and mag pouches. As it employs Ruger’s standard 10/22 action and standard 10-round rotary magazine, this gun should be very reliable. We’re anxious to test one of these bull barrel Rugers to assess its accuracy. It certainly makes for a compact and portable package. Is a take-down 10/22 (with suppressor of course) the ultimate “truck gun”?

No More NFA for Suppressors? Hearing Protection Act Would Change Everything…

suppressor silencer sound moderator NFA 1934 ATF hearing protection

New legislation by Congressman Matt Salmon* (R-AZ) would make it much easier to purchase a suppressor (aka “silencer” or “sound moderator”) for use with firearms. The new Hearing Protection Act (HPA), H.R. 3799, will remove suppressors from the purview of the National Firearms Act (NFA), replacing the current burdensome federal transfer process with a standard NICS background check. Under the proposed law, acquiring a suppressor would be like purchasing a firearm — you would obtain the suppressor from an FFL dealer after passing a background check. There would still be a background check, but suppressor purchasers would no longer be required to fill out extensive paperwork, be fingerprinted, and pay for a $200.00 tax stamp. The HPA also includes a provision to refund the $200 transfer tax to applicants who purchase a suppressor after October 22, 2015.

Many older hunters and sport shooters suffer from hearing loss. Greater access to suppressors would help prevent that health problem. “Suppressors significantly reduce the chance of hearing loss for anyone who enjoys the shooting sports,” said Chris Cox, executive director of NRA’s Institute for Legislative Action. On average, suppressors reduce the noise of a gunshot by 20 – 35 decibels (dB), roughly the same sound reduction as earplugs or earmuffs. In addition to hearing protection, suppressors also mitigate noise complaints from those who live near shooting ranges and hunting lands.

Because suppressors safeguard hearing and reduce “noise pollution”, suppressors are widely used in many countries, including the United Kingdom. In most parts of Europe, suppressors are readily available at reasonable cost. According to the NRA-ILA, “Many European nations place no regulations on [suppressor] acquisition or use.” In the “enlightened” European view, sound moderators are considered a “good thing”. Is it time for the USA to change its laws?

It’s Time to Remove Unnecessary Burdens to Suppressor Ownership
Suppressors have been federally regulated since the passage of the National Firearms Act of 1934. The NFA regulates the transfer and possession of certain types of firearms and devices, including suppressors. Currently, prospective buyers must send in a Form 4 application to the ATF, pay a $200 transfer tax per suppressor, undergo the same background check that is required to purchase a machine gun, get a “CLEO Signoff”, and wait months for the ATF to process and approve the paperwork.

The American Suppressor Association (ASA) states that: “[The] Hearing Protection Act will fix the flawed federal treatment of suppressors, making it easier for hunters and sportsmen to protect their hearing in the 41 states where private suppressor ownership is currently legal, and the 37 states where hunting with a suppressor is legal. This legislation will remove suppressors from the onerous requirements of the NFA, and instead require purchasers to pass an instant NICS check, the same background check that is used during the sale of long guns.”

suppressor moderator silencer hearing protection act HPA

There has been a huge growth in the number of registered suppressors in the USA. From 2014 to 2015, the number of NFA-registered suppressors rose from 571,150 to 792,282. That’s a 39% increase in just one year! It’s remarkable that there are nearly 800,000 suppressors now registered in the USA. These stats are based on data published in the latest Bureau of Alcohol, Tobacco, Firearms, and Explosives (BATFE) Firearms Commerce Report.

Matt Salmon as co-sponsors of H.R. 3799, the Hearing Protection Act (HPA), are ten other U.S. Representatives: Frank Guinta (R-NH), John Carter (R-TX), Mike Kelly (R-PA), Chris Collins (R-NY), Glenn Thompson (R-PA), Tim Huelskamp (R-KS), Trent Franks (R-AZ), Mia Love (R-UT), Doug LaMalfa (R-CA), and Chris Stewart (R-UT).

Muzzle Brake Noise Levels Tested by PrecisionRifleBlog.com

PrecisionRifleBlog.com Cal Zant Muzzle Brake Test Noise Level Decibels Suppressor

Cal Zant at PrecisionRifleBlog.com continues to crank out interesting results from his recent muzzle brake field test. Cal recently released his muzzle brake sound test results, which gives us hard data on 20 different muzzle brakes.

Sound can be a tricky subject, but Cal Zant, the editor of PrecisionRifleBlog.com, presents everything an informed shooter should know about muzzle brake noise in a straightforward and practical way. Most sound tests are measured from the side of the muzzle, in accordance with mil-spec standards, and Cal did that. But he also measured the sound level of each brake from behind the rifle, closer to the shooter’s position. This provides a more accurate indicator of the actual sound levels firearms operators will encounter while shooting.

Muzzle brakes ARE really loud — that’s something most active shooters have observed. But this study finally gives us some hard data and makes objective comparisons. The difference between brakes was quite significant. Some brakes were ear-splitting — more than twice as loud as other brakes tested.

As a bonus, Cal also provides data on how the new Ultra series suppressors from Thunder Beast Arms Corp (TBAC) compare in terms of sound level behind the rifle.

39% Increase in Suppressor Ownership in Past Year

Can Suppressor Moderator Silencer BATFE ATF Guns.com Registered NFA 800,000 suppressors in USA

There has been a huge growth in the number of registered suppressors in the USA. From 2014 to 2015, the number of NFA-registered suppressors rose from 571,150 to 792,282. That’s a 39% increase in just one year! It’s remarkable that there are nearly 800,000 suppressors now registered in the USA. These stats are based on data published in the latest Bureau of Alcohol, Tobacco, Firearms, and Explosives (BATFE) Firearms Commerce Report.

According to Knox Williams, president of the American Suppressor Association, “The suppressor market grew more [from 2014-2015] than it did in the previous two years combined. This unprecedented growth is in large part due to educational initiatives, and the passage of 11 pro-suppressor laws and regulations last year.” (Source: Guns.com.)

We expect suppressors (also known as “cans”, “silencers” or “sound moderators”) to become even more popular in the years to come. This trend will continue: “As more target shooters and hunters realize the many benefits suppressors provide, their popularity across the United States will continue to increase,” said NSSF Senior Vice president and General Counsel Larry Keane.

Texas Leads the Way in Suppressor Ownership
Currently, 41 states permit ownership of Federally-registered suppressors. While suppressor ownership rates are increasing in all those 41 states, forty percent (40%) of all registered suppressors are found in five key states: Texas (130,769), Georgia (59,942), Florida (50,422), Utah (50,291) and Oklahoma (27,874).

Muzzle Brake Comparison Test by Precision Rifle Blog

Cal Zant Precison Rifle Blog AccurateShooter Muzzle Brake Test Noise Recoil Reduction Video

Another massive, data-driven field test has been completed by our friend, Cal Zant, over at PrecisionRifleBlog.com. The past few months, Cal has tested 20+ muzzle brakes designed for 6mm, 6.5mm, and .30-caliber precision rifles. Hundreds of hours have gone into this research, and it provides a lot of new insight and empirical data for several aspects of muzzle devices. Cal put a huge amount of labor/engineering into these tests and his findings deserve to be widely read.

CLICK HERE for PRB Muzzle Brake Test Overview | CLICK HERE for 6mm + 6.5mm Brake Test Results

PRB Muzzle Brake Test Methodology

Recoil Reduction
Cal created a system to directly measure the entire recoil force signature of each muzzle brake using high-speed sensors. Although the recoil cycle happens very quickly (around 1/100th of a second), his test equipment could record up to 1,000 force data points during a single recoil cycle! He fired over 1,000 rounds of match-grade ammo through four different rifles: 6XC, 6.5 Creedmoor, .308 Win, and the monster .300 Norma Magnum. He literally spent thousands of dollars on this part of the test, to ensure he got it right.

Cartridge Types Tested: 6XC, 6.5 Creedmoor, .308 Win, and .300 Norma Magnum

Ability To Stay On Target
David Tubb helped Cal develop this part of the test, because David believes this is the most important aspect of a muzzle brake. Using a laser and high-speed camera, Cal was able to objectively quantify how well each design helped you stay on target.

Noise Level
Muzzle brakes are loud, but some are louder than others … three to four times as loud. Cal enlisted the help of an expert from the suppressor industry to precisely measure how much louder each muzzle brake made a rifle. Each brake was tested in accordance with MIL-STD-1474D using calibrated military-approved equipment, and the noise level was also tested at the shooter’s position. This produced some interesting results.

Zant also includes high-res photos of each brake, and plans to publish other info about each model (including price, whether it requires gunsmithing, what calibers it is available in, etc.) to make it easy to compare them side-by-side.

Cal recently started publishing the results of these tests, and there is already a lot of interesting info. The data might surprise a few people and even dispel a few myths. Particularly interesting is Zant’s comparison of recoil reduction with a suppressor compared to muzzle brakes. How do you think the suppressor performed compared to the brakes? You may be surprised.

UPS Now Refuses to Ship Suppressors (Silencers)

TBAC suppressor silencer

The National Shooting Sports Foundation (NSSF) this week learned that United Parcel Service (UPS) has apparently changed its policy regarding the shipment of firearms suppressors. According to the NSSF, a new policy is in effect at UPS facilities nationwide. This new policy states that UPS will no longer ship suppressors, even between Federal licensees.
TBAC suppressor silencer

NSSF representatives are now trying to find out why UPS has changed its shipping policies:

“NSSF is working with UPS executives to determine what prompted the enforcement of this unwarranted policy. We are unaware of any thefts or losses that would explain the shipping company’s sudden decision to enforce a prohibition against shipment. NSSF will keep you apprised of developments. Separately, NSSF is also working with the U.S. State Department to achieve a change of policy to allow export of suppressors.”
