Q & A: TOP TEN Questions about Suppressors Answered HERE »

You’d like to protect your hearing, and maybe you’re a little curious about how your rifle might shoot suppressed. So you’re thinking of buying a suppressor (aka “can”, “moderator”, “silencer”). You can’t just get one off the shelf at Walmart. Acquiring a suppressor requires filling out paperwork and paying a Federal $200 Tax Stamp. Plus there is typically a pretty long wait. However, the good news is that suppressor ownership is now legal in 42 of the 50 American states — that’s 84%! For most American adults, getting a suppressor is legal, provided pass the required background checks.

States Where Suppressor Ownership is Allowed
Currently, the following 42 states allow private ownership of suppressors: AL, AK, AZ, AR, CO, CT, FL, GA, ID, IN, IA, KS, KY, LA, ME, MD, MI, MN, MS, MO, MT, NE, NV, NH, NM, NC, ND, OH, OK, OR, PA, SC, SD, TN, TX, UT, VT, VA, WA, WV, WI, WY.

Note: Even if you live in one of the states listed, you should still verify that owning a suppressor is legal in your area. Some states may have municipal- or county-based restrictions.

States Where Suppressor Ownership is Prohibited
Unfortunately, there are still eight (8) States that forbid private ownership of suppressors. The eight No-Go States are: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, Rhode Island. In these eight states, private ownership of suppressors (aka “silencers”) is forbidden. Hopefully that a few of those eight hold-out states will change their laws in the months ahead.

Looking Inside a Suppressor in Action
Popular YouTube Channel Smarter Every Day recently released a cool video featuring rifle suppressors with see-through acrylic sleeves. The team filmed shots through the suppressors using ultra-high-speed (110,000 frame per second) cameras. When played back in super-slow-motion, you can see the flame propagate through the suppressor and the bullet move through each baffle before it exists the muzzle. Watch the results in the video below — it’s mesmerizing:

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.

Suppressors serve one main purposes — to reduce the sound levels produced when firing pistol or rifle rounds. But GunsAmerica Digest editor True Pearce notes there are many other reasons to own a suppressor. A suppressor can reduce muzzle blast and felt recoil. The suppressor may prevent hearing damage that occurs through bone conduction better than earplugs and muffs because it reduces the noise energy at the source. When hunting, the reduced shot noise can help avoid spooking game. Having a suppressor also makes it easier to communicate when working as a team on a hunt. And, when compared to a muzzle BRAKE, suppressors are much less likely to kick up dust, dirt, sand, and snow when you shoot prone. READ FULL ARTICLE on GunsAmerica Digest.

There is some confusion surrounding the laws concerning suppressors, which are now legal in 42 U.S. States. In most jurisdictions that allow suppressor ownership, no additional state permit or license is required. But you do have to comply with Federal requirements when acquiring the suppressor. You may wish to create a trust to own the suppressor — there are some important practical advantages to having a suppressor trust. The Traditional NFA Gun Trust allows multiple responsible parties, i.e. “trustees”, to legally have possession of the suppressor. Each trustee must be verified and for each suppressor owned by the trust there will be a $200 Tax Stamp. READ FULL ARTICLE on GunsAmerica Digest.

How to Choose A Suppressor »

Suppressor Academy GunsAmerica Digest silencer central

When shopping for a suppressor there are many factors to consider: price, build quality, materials, sound level reduction effectiveness, weight, ease of mounting, and ease of cleaning and maintenance. We recommend that all suppressor buyers research the options. Check the manufacturer’s reputation, check diagrams for disassembly and maintenance. There are always trade-offs. Shorter suppressors may save some weight, but if they don’t cut the decibels as well you may be disappointed. You also need to consider the caliber — will your suppressor be used on multiple firearms? If so then get one that fits the largest caliber you will shoot. READ FULL ARTICLE on GunsAmerica Digest.

Don’t Get Barrel-Busted! Federal Barrel Length Requirements

short barrel barreled rifle shotgun NSA tax stamp ATF legal brief guncollective.com

The Legal Brief is a feature of TheGuncollective.com that focuses on firearms rules and regulations. In this Legal Brief video, Attorney Adam Kraut explains key State and Federal regulations governing firearms, and explains how to ensure compliance with all applicable laws.

This five-minute video explains barrel length rules for rifles and shotguns, and also explains the best (and most fool-proof) methods to measure your barrel. In addition, the video explains how to measure firearm overall length. A rifle or shotgun which is less than 26 inches overall can also be classified as a “Short-barreled” rifle/shotgun subject to the NFA. NOTE: Under federal law “If the rifle or shotgun has a collapsible stock, the overall length is measured with the stock EXTENDED”.

Highlights of LEGAL BRIEF Discussion of Barrel Length and Firearm Overall Length

The ATF procedure to measure the length of a barrel is to measure from the closed bolt or breech face to the furthest end of the barrel or permanently attached muzzle device. ATF considers a muzzle device that has been permanently attached to be part of the barrel and therefore counts towards the length.

How to Measure Barrel Length: Drop [a] dowel or rod into the barrel until it touches the bolt or breech face, which has to be closed. Mark the outside of the rod at the end of the muzzle crown (if you don’t have a permanently attached muzzle device) or at the end of the muzzle device if it is permanently attached. Remove the rod and measure from the mark to the end of the rod. That is your barrel length[.]

Remember, if the barrel length is less than 16 inches, it is possible that the firearm could be a short barrel rifle (if you are building a rifle or it is already on a rifle) and if the barrel length is less than 18 inches, it is possible the firearm could be a short barrel shotgun (again if you are building a shotgun or it is already a shotgun). Both of these firearms would be subject to the purview of the National Firearms Act and would require the firearm to be registered accordingly.

How to Measure Overall Length:The overall length of your rifle or shotgun may also classify it as a Short Barrel Rifle or Short Barrel Shotgun. The overall length of a firearm is the distance between the muzzle of the barrel and the rearmost portion of the weapon measured on a line parallel to the axis of the bore. … If the rifle has a permanently attached muzzle device, that is part of the overall length. … If the rifle or shotgun has a collapsible stock, the overall length is measured with the stock extended.

Suppressors for Hunting — What You Need to Know

There is an informative article on the NRA’s American Hunter website regarding suppressor use for hunting. The article, What Hunters Need to Know About Suppressors, answers common questions about licensing, tax stamps, and suppressor types. The article explains the history of the $200 tax stamp which must be paid when acquiring a suppressor:

“Why the Tax? In 1934 … the federal government, while battling gangsters such as Al Capone, heavily restricted silencers with passage of the first National Firearms Act. Hoping to gain an advantage on criminals that often had better weapons than cops, the Feds placed a mandatory ‘sin’ tax on silencers that was so high it would effectively ban their purchase by all but the wealthiest individuals. In 1934, $200 was the equivalent of $3,500 today. The $200 tax still stands despite no evidence that a simple metal tube is capable of causing crime.” — American Hunter

The American Hunter article also discusses how well suppressors actually reduce noise. User should be aware that the sound level of a large, centerfire hunting cartridge will still exceed 130 decibels (dB) on average, even with a typical suppressor (silencer) in place. For that reason, we recommend that hunters continue to wear ear protection even when they shoot suppressed.

For example, Thunder Beast Arms says its latest Ultra 9 Suppressor will reduce the report of a .308 Win to 132-134 dB: “The ULTRA 9 will suppress a typical .308 bolt-action rifle down to approx. 132-134 dB. It also has very little or no ‘first round pop’ (FRP) in most applications.” NOTE: These dB levels are measured in accordance with MIL-STD-1474D using BK 2209 SLM offset one meter from muzzle.

How Loud Are Unsuppressed Rifles?
Firearms Are Loud — 140 dB to 175 dB. Audiology group ASHA explains: “Almost all firearms create noise that is over the 140-dB level. Exposure to noise greater than 140 dB can permanently damage hearing. 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.

suppressor fact and fiction moderator silencer

How Much Does a Good Suppressor Really Reduce Firearm Sound Levels?
That depends on the rifle, the cartridge, and the effectiveness of the suppressor. The American Hunter article explains: “Suppressors retard the speed of propellant gases from the cartridge that rapidly expand and rush out of the barrel. It’s these gases that produce the loud boom that’s heard for miles. A suppressor’s series of internal baffles slows these gases so they are not all released at once, thereby muffling the sound.” Many good commercial suppressors can achieve 30-35 dB sound suppression. However, Zak Smith of Thunder Beast Arms says: “There are a bunch of manufacturers who publish values that are not reproducible, or use an ad-hoc test instead of a mil-spec test. In many cases we’ve tested the exact same suppressors they’ve advertised with 30-40 dB reductions and found they are actually in the high 20s instead.”

Again, for this reason, we recommend that hunters use ear protection, such as electronic muffs, even when shooting suppressed.

Choosing a Suppressor for Hunting Use
The American Hunter article explains that there are many types of suppressors on the market. Bigger suppressors are heavier, but they normally are more effective. You also have a choice in muzzle attachments:

“For most hunting applications, direct thread is the best choice. If you intend to buy only one suppressor yet you have multiple guns, it’s advantageous to buy a model sized and rated for the largest caliber you intend to use. While a suppressor made specifically for a .223 Rem. will reduce the sound of that round slightly better than a model made for .30 caliber, for example, you can use a .30-caliber can for smaller calibers — but not vice-versa. In general, the bigger the can, the more it reduces sound. Smaller suppressors, however, are easier to carry in the woods.” — American Hunter


Chart from American Suppressor Association.

States Where Suppressor Ownership is Allowed
Currently, the following 42 states allow private ownership of suppressors: AL, AK, AZ, AR, CO, CT, FL, GA, ID, IN, IA, KS, KY, LA, ME, MD, MI, MN, MS, MO, MT, NE, NV, NH, NM, NC, ND, OH, OK, OR, PA, SC, SD, TN, TX, UT, VT, VA, WA, WV, WI, WY. NOTE: Suppressors are legal in Connecticut and Vermont, but hunting with silencers is not allowed in those states.

How to Apply for a Suppressor
To acquire a quality suppressor, you’ll first need to shop around, comparing verified performance. Unfortunately some manufacturer’s dB claims are exaggerated. Give due consideration to size, weight, and durability. When you’ve selected a brand and model, find a Class 3 dealer authorized by the ATF to sell suppressors. You must fill out ATF Form 4, get fingerprinted, and pass a background check. Along with two completed copies of Form 4, submit your fingerprint card, passport photo and a check for $200 to the ATF. Then you wait for the ATF to process your application. American Hunter says the average ATF suppressor processing wait time is now nine months.

BENEFITS OF SILENCERS

NOISE REDUCTION
According to OSHA, the threshold for a hearing safe impulse noise is 140 dB. Without hearing protection, exposure to any impulse noise over 140 dB causes varying degrees of permanent noise-induced hearing loss, which can also lead to tinnitus. Most well-engineered silencers take the dB level of their host firearm well below 140 dB, making those silencers effective primary hearing safety devices. You should always still wear hearing protection (muffs or plugs) when using suppressors.

RECOIL REDUCTION
By containing the explosion at the muzzle, suppressors significantly reduce perceived recoil energy, reduce the rifle’s rearward movement on recoil, and reduce rifle torquing and muzzle flip. The reduction of recoil (and rifle torquing/hopping) lessens shooter fatigue and helps the shooter get his sight picture back on target rapidly after firing. With smaller calibers, a suppressor may enable the shooter to maintain a nearly-continuous sight picture, following the shot into the target. In addition, by reducing felt recoil (and muzzle blast), a suppressor can help inexperienced shooters avoid flinching.

Hands On with SilencerCo Suppressors — Range Time in WA

SilencerCo Suppressor Hybrid 300 Omega Osprey moderator sound

Our friend Gavin Gear of UlimateReloader.com recently visited a SilencerCo dealer in the state of Washington, The Range LLC in Yakima, WA. Gavin was able to test a number of suppressors (aka “moderators” or “silencers”) for both rifle and pistols. Gavin recently released a lengthy article covering his experiences. If you are in the market for a suppressor, we highly recommend you read Gavin’s SilencerCo Products Overview on UltimateReloader.com.

Gavin was able to test three SilencerCo suppressors: the Omega 300, the Hybrid, and the Osprey 45. In addition Gavin was able to handle the Maxim 9, an integrally suppressed 9mm handgun.

SilencerCo Suppressor Hybrid 300 Omega Osprey moderator sound

Gavin reports the Omega 300, which is rated up to .300 Winchester Magnum, is a very popular “can”. According to Gavin, the Omega 300 has become the best-selling rifle suppressor in history for important reasons. First, it has an integral muzzle brake. Second, it can work for multiple calibers, from .223 up to .308. Third, “It is very tough — .300 Win Mag rated, and full-auto rated”.

SilencerCo Suppressor Hybrid 300 Omega Osprey moderator sound
SilencerCo lineup, from left: Omega 300, Hybrid, Osprey 45

Gavin says the Hybrid Suppressor is an interesting concept: “One suppressor that you can configure for multiple calibers, both rifle and pistol. This includes the ability to change out the threaded mount on the muzzle end, and you can also swap out end caps that will optimize sound suppression for different calibers. The Hybrid… is full-auto rated, and can handle rifle cartridges up to and including .338 Lapua Magnum! But this suppressor can also be used for pistol applications…from 9mm up to 44 ACP.”

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.

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.

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.”

Silencer Shop Makes It Easy to Acquire and Register Suppressors

Many of us would like to outfit one (or more) of our rifles with a suppressor, but the cost and red tape involved can be daunting. Some states prohibit private individuals from owning suppressors. However, most U.S. states DO allow suppressor ownership. That’s the good news. On the other hand, suppressors are not inexpensive and the process of obtaining governmental approval is time-consuming. Then there is the cost of the tax stamp itself — $200.00 for each silencer you own.

Nonetheless, suppressors are fun, and they serve an important function. Along with protecting your hearing, suppressors can tame recoil and dramatically reduce muzzle flash. Noise reduction of up to 35 decibels is possible with a .223 Rem. When shooting any firearm, you should still wear hearing protection of course, but suppressors can help reduce the risk of permanent hearing damage.

Benefits of a Suppressor — Why Suppressors Make Sense:

Is It Legal For You To Own A Silencer?
The vast majority of the 50 states permit citizens to own silencers. Currently, the following states allow private ownership of suppressors: AL, AR, AK, AZ, CO, CT, FL, GA, ID, IN, KS, KY, LA, ME, MD, MI, MO, MS, MT, ND, NE, NV, NH, NM, NC, OH, OK, OR, PA, SC, SD, TN, TX, UT, VA, WA, WI, WV, and WY. Even if you live in one of these states, you should verify that owning a suppressor is legal in your city/county.

If you live in a state where suppressor ownership is legal, and you can legally own a firearm, then you can buy a suppressor. However, you need to obtain ATF permission and pay a tax.

If you are interested in getting a suppressor, thankfully there is a source that can help you select the right product, and fill out all the paperwork required.

Huge Arsenal of Tommy Guns Set for Auction in St. Louis

St. Louis police thompson tommy gun auction NFA saleIt is an iconic American firearm design — the Thompson submachine gun, or “Tommy Gun”. Here’s your chance to add the real thing to your firearms collection. The St. Louis Metropolitan Police Department (SLPD) plans to auction off twenty-nine (29) historic Tommy Guns. These 1920s-era .45-caliber weapons have been stored in a vault for decades. The SLPD is selling the highly-collectible submachine guns to raise money for new service pistols for its officers. The auction will take place later this year, but no exact auction date has yet been set.

A Million Dollars Worth of Full-Auto Firepower
The Tommy guns are expected to fetch from $15,000 to $40,000 each, putting a estimated value of the whole collection at as much as $1,000,000. According to the Washington Times: “The collection was appraised by a local dealer in 2012 at $770,000, but police and some collectors believe it could sell for much more. The collection includes rare 1921 and 1927 Colts and a model made in 1942.”

SLPD chief Sam Dotson stated: “We’re told [that] outside of the military and federal government we have the largest cache of Thompson machine guns.”


Because these are fully-automatic “Class III” weapons, subject to the National Firearms Act (NFA), purchasers much fill out the proper paperwork, pass background checks, and obtain a Federal Tax stamp for each Tommy gun purchased. The SLPD expects the majority of the firearms will be purchased by wealthy collectors or museums.
