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.

The high speed transparent silencer video is pretty neat. It certainly demonstrates, to some extent, the violence that happens inside centerfire rifle suppressor when firing.
At Thunder Beast Arms Corp. we have carefully studied the forces/pressures operating inside suppressors. The “uncorking” pressure when the bullet exits the muzzle is typically in the 8,000 to 15,000 psi range, but some combinations of cartridge and barrel length can extend this up to the 25,000 psi range. Job #1 of a suppressor designer is to build a suppressor that won’t explode. Job #2 is to build one that quiets down the muzzle report significantly. Doing that well, with the minimum amount of material, is the tricky part.
Suppressor design is both art and science, and we approach our R&D from three sides: experience, experimental testing, and computation.
There are a lot of opinions about how to design a quiet suppressor. Many of these are based on preconceived notions of how suppression “should work”. These theories may or may not work when built and tested in the real world. Where the rubber hits the road is experimental testing. I would say that a majority of knowledge about “How to design a quiet suppressor” comes from building hundreds or thousands of prototypes and testing them with good equipment in a cogent experimental process. Some of those theories pan out, but many of them do not.
Thunder Beast Arms Tests its Suppressors in the Lab and in the Field.
Scientific Software Aids Design
We have also made a large investment in computation fluid dynamics (CFD) and finite-element analysis (FEA) software and use it in addition to other computer-model analysis to look at the physics that occurs inside the suppressor. This type of analysis gives information about material effects that is pretty much impossible to get any other way. Even so, the computer cannot tell you how to design a
suppressor, and the results must always be checked and compared to reality.
Thunder Beast Arms Corporation was started ten years ago with the goal of producing the best precision rifle suppressors. Our current ULTRA series in .223, 6.5 mm, .308, and .338 calibers provides industry-leading suppression performance with very light weight.

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.

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 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.
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.
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.

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.

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.
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.”
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.”

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.”
“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.”
“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.”
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.”

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.”
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.”
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.

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).
The high speed transparent silencer video is pretty neat. It certainly demonstrates, to some extent, the violence that happens inside centerfire rifle suppressor when firing.
