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.
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
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, but hunting with silencers is not allowed in Connecticut.
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.
So you’re thinking of buying a suppressor (aka “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 the buyer passes the required background checks (explained below). The 42 “suppressor-friendly” states are shown as RED in the illustration below.

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.
“Suppressor ownership [has] boomed in the 21st century. Thanks in part to companies like Silencer Central that streamline the purchasing process, the number of registered suppressors has grown from 285,000 in 2010 to over 2.6 million in 2020.” — GunsAmerica Digest
States Which Prohibit Suppressor Ownership
The eight states which prohibit suppressor ownership are: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island. These states are shown in GRAY in the map.
Good News — Suppressor Tax Will Be Eliminated Next Year
The suppressor transfer tax has not been eliminated yet, but it will be reduced to $0 (zero) starting January 1, 2026. This law change was effectuated by recent Federal legislation through Congress and signed by President Trump. The “One Big Beautiful Bill”, passed by Congress and signed into law by President Trump on July 4, 2025, includes a provision reducing the NFA tax stamp on suppressors and short-barreled firearms to $0. The Silenco Video below from 8/4/2025 explains the new law changes.
Current Status: As of today, August 10, 2025, the $200 tax stamp is still required for the purchase of suppressors and other NFA items.
Effective Date: This change to a $0 tax stamp will take effect on January 1, 2026.
Interim Period (August 2025 – December 2025): Some retailers, like Silencer Central, are offering promotions to cover the $200 tax stamp fee on select suppressors purchased before the $0 tax stamp becomes effective, according to Silencer Central.
NFA Regulations Still Apply: Even after the tax stamp is eliminated in 2026, suppressors will still be regulated under the National Firearms Act (NFA). This means you’ll still need to go through the ATF process, including fingerprinting and background checks, to acquire a suppressor.
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. According to the American Suppressor Association, to own a suppressor in the United States you must:
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. NOTE: This tax will be eliminated as of 1/1/2026.
*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.
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.
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.

Good news for gun owners — we are a step closer to the elimination of the $200 National Firearms Act taxes on suppressors and short-barreled guns. After passage of the Big Beautiful Bill in the House of Representatives, the U.S. Senate Finance Committee officially advanced language to fully repeal the excise taxes imposed under the National Firearms Act (NFA).
Thanks to aggressive advocacy from Gun Owners of America (GOA) and mounting grassroots pressure, the Senate’s version of the “One Big Beautiful Bill” now includes full repeal of the $200 NFA tax on:
This expands the House-passed repeal of the suppressor tax. The bill next heads to the “Byrd Bath” review, where non-budgetary provisions may be stripped, but because the NFA operates primarily as a tax mechanism — given that the Supreme Court held that the NFA is primarily a tax in Sonzinky v. U.S. (1937) — GOA feels strongly that the provision ought to survive.
Erich Pratt, GOA Senior V.P., stated: “The House opened the door — now the Senate is charging through it. The American people have been forced to pay hundreds of dollars and submit to federal gun registration just to own firearms that are protected by the Second Amendment[.] This is a monumental step toward dismantling the ATF’s unconstitutional enforcement regime, and the Senate must finish the job.”
Aidan Johnston, GOA Director of Federal Affairs, added: “The Senate Finance Committee’s move to fully repeal the unconstitutional and archaic National Firearms Act tax on short-barreled firearms and suppressors is the direct result of relentless pressure from GOA’s grassroots and our lobbying efforts on Capitol Hill. The government has no right to tax and register accessories like suppressors or firearms with short barrels.”
FPC Urges U.S. Senate to Pass Suppressor Reforms
The Firearms Policy Coalition (FPC) has urged the U.S. Senate to pass H.R. 1, the “One Big Beautiful Bill Act”, with the legislation’s current suppressor reforms intact.
Last month, the House of Representatives passed the Act with three important provisions relating to suppressors, one removing these hearing protection devices from the extreme regulations of the National Firearms Act (NFA) and two others zeroing out the current significant Federal fees that must be paid when acquiring a suppressor.
Research by the Centers for Disease Control and Prevention (CDC) has shown that “[t]he only potentially effective noise control method to reduce students’ or instructors’ noise exposure from gunfire is through the use of noise suppressors that can be attached to the end of the gun barrel.” The CDC’s conclusion has been affirmed by many other health experts. The American Academy of Otolaryngology-Head and Neck Surgery has endorsed “the use of firearm suppressors as an effective method of reducing the risk of hearing loss, especially when used in conjunction with conventional hearing protective measures”.

“Firearm suppressors are incredibly important hearing protection devices that reduce the risk of permanent damage and hearing loss for shooters and others nearby”, explained FPC President Brandon Combs. “These important safety tools are no different than hard hats, safety glasses, and fire extinguishers and should be widely available for personal use, not taxed out of the reach of ordinary Americans.”
Suppressors, On Average, Reduce Noise Levels about 30 Decibels
Suppressors work similar to a car’s muffler, redirecting exhaust gases. 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. In short, we can [expect] 30 dB of attenuation as an average.” Reducing gun shot noise to the 130dB range means that the sound level with NOT permanently damage hearing.
A Virginia Congressman has introduced legislation which will take suppressors (aka “silencers”) off the NFA list and make them much easier to purchase. That’s a good idea because a quality suppressor can reduce firearm sound levels by 30 decibels (dB) or more. U.S. Rep. Ben Cline’s Hearing Protection Act (H.R. 404) would remove firearm suppressors from the list of restricted items under the 1934 National Firearms Act (NFA). That would reduce costly licensing ($200 per suppressor) and burdensome background checks. Instead, suppressors would be regulated under the 1968 Gun Control Act (GCA) with the same type of background check done with retail firearm purchases. The legislation would also amend statutory suppressor definitions.
Under current law, an individual purchasing a suppressor must locate a regulated NFA Class III retailer, complete a Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Form 4 with the model and serial number of the suppressor, and obtain two passport photos and fingerprint cards from a local police department. The local chief law enforcement official must receive a completed copy of the application. Then the form, photographs, and fingerprints must be sent to ATF along with a check to pay the $200 tax. The customer can obtain the suppressor from the NFA Class III retailer upon an additional background check through FBI’s National Instant Criminal Background Check System (NICS).
Congressman Cline’s legislation would eliminate those requirements and make suppressors available with the same type of paperwork and background check required for a firearm. H.R. 404 would also clarify the definition of suppressors, ensuring that components like mounts, baffles and end caps are not erroneously classified as standalone suppressors or “silencers”.
“Congressman Cline’s Hearing Protection Act will have the federal government recognize firearm suppressors for what they are. These are accessories to a firearm that make recreational shooting and hunting a safer experience”, said Lawrence G. Keane, NSSF Senior V.P. and General Counsel. “These safety devices reduce the report of a firearm to a level that won’t cause instant and permanent hearing damage.” There are currently 2.6 million legally owned suppressors in the United States.

Firearm suppressors (aka “silencers”) reduce the report of a firearm from a level roughly equal to that of a jet taking off which causes instant and permanent hearing loss to one that is safe, but still equal to a jackhammer. That decibel level will not permanently damage hearing. Suppressors work similar to a car’s muffler, redirecting exhaust gases.

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:
