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.

Protect Your Hearing — Wear Protection Whenever You Shoot
Noise-induced hearing loss and tinnitus are two of the most common afflictions for recreational shooters and hunters. Everyone knows that gunfire is loud, but very few people understand the repercussions that shooting can have on their hearing until it’s too late.
The better quality suppressors can reduce the noise of a gunshot by 20 to 35 decibels (dB). Good muffs or plugs will reduce sound by 23 to 33 dB. By decreasing the overall sound signature, suppressors help to preserve the hearing of recreational shooters and hunters. Even the most effective suppressors, on the smallest and quietest calibers (.22 LR) reduce the peak sound level of a gunshot to between 110 to 120 dB. To put that in perspective, according to the National Institute for Occupational Safety and Health (NIOSH), that is as loud as a jackhammer (110 dB) or an ambulance siren (120 dB). For normal caliber handguns and rifles, suppressed sound levels routinely exceed 130 dB, just shy of OSHA’s “hearing safe” threshold of 140 dB.
According to Dr. William W. Clark, the current Director of the Washington Univ. School of Medicine’s Audiology/Communication Sciences Program, a “serious threat to hearing comes from recreational hunting or target shooting”. This is in large part due to the fact that many people choose not to use traditional hearing protection devices like earplugs and earmuffs because they want to be able to hear their surroundings. Multiple studies have found that between 70 to 80% of hunters never wear earplugs or earmuffs, and nearly half of all target shooters don’t consistently wear traditional hearing protection. Thus, it should come as no surprise that for every five years of hunting, hunters become seven percent more likely to experience high frequency hearing loss.
This article is based on information from the American Suppressor Association (ASA). Since the ASA’s formation in 2011, three additional states have legalized suppressor ownership and 18 states have legalized suppressor hunting. For more information, visit www.AmericanSuppressorAssociation.com.

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.

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.
Share the post "Why You Still Need Hearing Protection When Using Suppressors"
Are sound suppressors useful in competition shooting? In some disciplines, and in venues where sound “moderators” are permitted, the answer is “yes”. In a past edition of Shooting Sports USA eZine, you’ll find an interesting article about the use of sound suppressors (aka “cans”). The article explores the use of suppressors in Europe and in tactical matches in North America. You’ll also find an explanation of the rules and regulations governing suppressor ownership and use in the United States.
Shooting Sports Editor Chip Lohman tests three rifles from the bench and found that sound suppressors did not harm accuracy. In fact, all three test rifles (one each in .223 Rem, .308 Win, and .338 Lapua Magnum), shot slightly better 5-shot groups at 200 yards when a suppressor was fitted to the barrel. However, the suppressors did alter point of impact. Interestingly, velocity standard deviation (SD) values were lower with suppressors in place for all three test rifles. This observation calls for further study.*
So the use of suppressors in competition could be a good thing. However, in the United States, current NRA rules prohibit the use of sound suppressors. NRA Rule 3.16.1 subsection (a) states: “Sound Suppressors are not authorized for use in High Power competition.” In addition, there are some practical problems with suppressors — the heat rising off of a naked suppressor can create mirage problems (that’s why some shooters wrap their cans with a cover).
Despite such issues, now commonly see suppressors on rifles used in tactical matches and PRS/NRL events. For example, many competitors in the Steel Safari field challenge match use suppressors. The photo below shows our friend Zak Smith competing in the Steel Safari with his suppressed Accuracy International rifle.
Commentary — What Can We Conclude?
Obviously, this three-rifle SSUSA test was not definitive. One well might observe different results with different types of suppressors, fitted to different kinds of rifles. Mounting a suppressor to any barrel will certainly affect harmonics and “tune”. But this SSUSA study does suggest that tactical shooters, who are allowed to use suppressors in competition, may find that the benefits of suppressors (significantly reduced recoil and less noise) outweigh any meaningful accuracy loss, at least in PRS-type matches.
NOTE: The article cautions that one should not extrapolate too much from the SD numbers, given the low number of test shots. Chronograph-maker Ken Oehler, when asked to comment on the SD values stated: “[You should] report the observed SDs, but draw no conclusions until… you can do more testing with larger sample sizes.”
Qualifications to Obtain a Suppressor
To legally obtain a suppressor, you must fill out Federal Forms and pay a $200 fee to the ATF. You must also pass BATFE background checks and otherwise comply with Federal and state laws. States can regulate suppressor ownership or use, so be sure to check the laws in your area. On the federal level, the process to acquire a suppressor is regulated under the National Firearms Act of 1934.
Thank to efforts by the NSSF, and the ATF adopting eForms, you can now get a suppressor purchase authorization with a far shorter wait time. NSSF began working to improve ATF NFA form processing in 2013 when it pressed the agency to institute electronic form processing, or eForms. This has had significant positive effects in reducing NFA wait times. As a result you can pay the required Federal $200 tax and obtain suppressor purchase authorization much more quickly.
Suppressors are now legal in 42 U.S. States. There are certain legal requirements for obtaining a suppressor, including paying a $200 Tax Stamp. To own a suppressor you must be legally eligible to purchase a firearm, pass a BATFE background check, pay a one time $200 Transfer Tax, and satisfy age requirements. The process for paying the $200 requires submitting an ATF Form 4 for each suppressor that you purchase. You can submit either electronically or via paper. The Form 4 authorizes transfer of the suppressor from the dealer or manufacturer to you. MORE INFO HERE.
A significant drop in processing wait times on submitted National Firearms Act (NFA) forms is shown in a new Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) report. The ATF has revealed that the average wait time on a paper NFA Form 4 — the most popular NFA form submitted — dropped to an average of 245 days for processing, while average processing times for electronic eForm 4s dropped to 53 days. Previously, wait times on Form 4s were near 280 days for paper form processing and between 90 and 190 days for electronic processing. NSSF has learned that in some cases fully electronic Form 4s were processed in as few as four days and in some cases on the same day.
Form 3 processing times also dropped with reports of of them being processed in as few as four days. Form 5 processing wait times for the tax-exempt transfer and registration of firearms dropped down to 19 days for paper forms and an average of one day for the electronic form.
OPINION: Suppressors Should Not Be Subject to NFA Regulation
NSSF continues to support the Hearing Protection Act and other proposed legislation that would remove silencers, commonly called suppressors, from the National Firearms Act. Suppressors are devices that provide hearing protection for hunters and target shooters. They are legal to own in 43 states and to hunt with in 42 states. Removing suppressors from the NFA would free up considerable ATF resources unnecessarily spent processing paperwork.

With over 340 shooting-related videos, the Alabama Arsenal YouTube Channel is a remarkable resource. This video channel provides detailed field tests of tactical-type rifles, ARs, and pistols. The testers have access to some very impressive ranges, and many of the tests are far more thorough than you’ll typically find with most gun magazines and gun-centric YouTube channels. For example, Alabama Arsenal (AA) has a series of 1000+ round pistol test videos. These are well worth watching if you are considering purchase of a defensive handgun.
Today we showcase multiple rifle videos covering two centerfire rifles, and three precision rimfire rigs. After these field test videos, you’ll find an interesting technical video which investigates how suppressors can affect muzzle velocity.
Barrett MRAD .300 PRC at 2200 Yards — Extreme Long Range
Here’s a rugged tactical rifle put to the test at Extreme Long Range. This video, featuring a Barrett MRAD chambered for the .300 PRC cartridges, features accuracy testing out to 2200 yards (1.25 miles). There is some good drone footage covering the long path to the target. The shooter noted that the bullets fired from his .300 PRC “go sub-sonic somewhere between 1800 and 1900 yards”, creating additional ballistics challenges at this yardage.

In this video AA’s team reviews the Savage Elite Precision Rifle with MDT ACC Chassis. Retailing for about $1810.00 in 6mm Creedmoor, this is one of the better production class options for PRS and NRL competition. Starting at the 3:10 time-mark, the video shows how all the adjustments function on the MDC ACC Chassis. Guns America Digest did a full review of this rifle, and was quite impressed.
Rimfire .22 LR Bergara B-14R in WOOX Furiosa Hybrid Chassis
Alabama Arsenal recently tested a .22 LR Bergara B-14R rimfire rifle fitted with the WOOX Furiosa hybrid chassis system, an Italian-made product featuring wood sections over a strong aluminum core chassis. The bolt operation and ergonomics of the B-14R simulate a Remington 700 very closely, making this rifle good for rimfire cross-training. The B14-R model tested was the version with carbon-wrapped barrel.
The WOOX Furiosa is an innovative, unique aftermarket replacement chassis. This high-tech hybrid stock/chassis combines wood sections over a full-length, aerospace-grade aluminum skeleton chassis, giving it the “feel” of a wood stock with the strength and stability of a metal stock. We like the way the stock feels on the trigger hand in particular and the smooth wood cheekpiece is also very nice. Made in Italy, the Furiosa is offered in three versions all with wood sections on the forearm, grip area, and cheekpiece. Choose natural Walnut Brown, Micarta Black, or Midnight Grey. Alabama Arsenal tested a B14-R fitted with the Micarta Black version. Below are photos of a centerfire rifle in a WOOX Furiosa hybrid chassis, with the Brown Walnut elements.

Suppressors are now legal in 42 U.S. States. There are certain legal requirements for obtaining a suppressor, including paying a $200 Tax Stamp. To own a suppressor you must be legally eligible to purchase a firearm, pass a BATFE background check, pay a one time $200 Transfer Tax, and satisfy age requirements. (SEE ALL Requirements).

The eight (mostly blue) states which still prohibit civilian suppressor ownership are: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island. READ FULL ARTICLE on GunsAmerica Digest.
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.
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.

1. Be at least 21 years of age to purchase a suppressor from a dealer.
2. Be at least 18 years of age to purchase a suppressor from an individual on a Form 4 to Form 4 transfer (contingent on state laws).
3. Be at least 18 years of age to possess a suppressor as a beneficiary of a trust or as a member of a corporation (contingent on state laws).
4. Be a resident of the United States.
5. Be legally eligible to purchase a firearm.
6. Pass a BATFE background check with a typical process time of 8 to 10 months.
7. Pay a one time $200 Transfer Tax.
That fifth requirement, “be legally eligible to purchase a firearm”, involves a list of factors. The prohibitions are set forth in the “prohibited person” list found on ATF Form 4473.*

Suppressor Facts — What You Need to Know
In this infographic, the NSSF provides the history, specifications, benefits and uses of firearm suppressors. Don’t suppress your knowledge!
Suppressors reduce gunfire sound levels by using baffles that contain expanding gasses exiting a firearm’s muzzle when ammo is discharged. Suppressors are similar to car mufflers that were, in fact, developed in parallel by the same inventor in the early 1900s. Well-designed suppressors typically reduce the gun sound levels by 30-35 decibels (dB).
Suppressors are now legal in 42 states nationwide. Suppressors are becoming more popular even though it still takes many months to get approved. In fact, the total number of suppressors registered in the NFRTR is 2,664,775 as of May 2021. This represents a 30% increase (622,056) since April 2020. That’s a remarkable growth rate. And we believe the numbers have increased substantially in 2022 and 2023.

Informational Video about Rifle and Pistol Suppressors
Alabama Arsenal regularly tests its firearms with suppressors. Over time, the testing team has leaned much about modern sound moderators, comparing features and learning how to install and maintain quality suppressors. Here is an interesting video that shows how suppressors affect shot velocities.

Read full story in GunsAmerica Digest for all 18 reasons to own a suppressor.
Do you own a suppressor yet? If you live in a state where silencers are allowed, there are many good reasons to get a modern suppressor. The process for acquisition has been streamlined. Vendors such as SilencerCo can now handle most of the legal paperwork required. And the choice of suppressors is greater than ever before.
Along with basic noise reduction, what are the key reasons to get a suppressor? There are actually many. True Pearce, Editor of the GunsAmerica Digest, has written an excellent article about the benefits of suppressors: Why a Silencer Might Prevent Dementia & 17 Other Reasons You Need a Suppressor. Here are FIVE of the 18 reasons outlined in the article. We recommend you read the full story to access ALL 18 reasons. That full article has worthwhile insights for anyone considering getting a suppressor.
Reason — Protect Your Hearing
Owning and using a suppressor helps prevent hearing loss. Hearing loss is a legitimate health concern that all firearms owners should be concerned about. Firearms are loud. The average firearm without a suppressor is between 140-165 dB and creates what is called an impulse noise (i.e. a noise that lasts for less than one second).
OSHA’s limit for impact/impulse noise is 140 dB…. Every time you fire a gun (including a .22 LR) without hearing protection or a suppressor, you can permanently lose hearing and it never returns. Surgery and hearing aids cannot restore the hearing you lose — it’s gone forever. Suppressors do not make your gun silent! However, they can make the impulse noise much less than 140 dB.
Reason — Reduce Muzzle Blast
A suppressor reduces or eliminates muzzle blast. Traditionally, we associate flinching with recoil, and while recoil can contribute to flinching, many shooters are finding that when using a suppressor on a caliber with no recoil they don’t suffer from the concussion, noise, and blast. As a result, they don’t close their eyes, flinch, or jerk the trigger.
Reason — Reduce Felt Recoil
A suppressor … reduces recoil or kick. Nobody that’s telling the truth enjoys getting punched in the shoulder, and that’s essentially what happens when you shoot a lightweight centerfire magnum rifle. Suppressors are very effective at slowing the recoil down or [reducing it significantly]. I personally observed a small (70-lb) 12-year-old boy shoot a 5.5-pound 6.5 PRC with a suppressor. After shooting he got up smiling and said, “That didn’t kick at all!”.
Reason — Reduce Muzzle Rise to Keep Your View on Target
Suppressors reduce muzzle rise and make it possible to stay on target through your shot [so you can watch the trace and impact]. This allows you to make your own wind calls and corrections.
Reason — Reduce Dust and Dirt Kicked Up from Muzzle Blast
Suppressors prevent snow, dust, dirt, or other debris from blowing up when you shoot prone. If you’ve shot much with muzzle brakes, you know this is a real thing.
