Since the ASA’s formation in 2011:

∗ 18 states have legalized suppressor hunting ∗
∗ 3 states have legalized suppressor ownership ∗


Suppressors, also known as silencers, are the hearing protection of the 21st century sportsman. Despite common misconceptions, suppressors are not silent. They are simply mufflers for firearms, which function by trapping the expanding gasses at the muzzle and allowing them to slowly cool.


Suppressors are regulated under the National Firearms Act (NFA) of 1934, which falls under the purview of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). To legally purchase or possess a suppressor 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.
  8. Reside in one of the 42 states that currently allows civilian ownership of suppressors.

Benefits of Suppressors


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.

Suppressors reduce the noise of a gunshot by an average of 20 – 35 dB, which is roughly the same as earplugs or earmuffs. By decreasing the overall sound signature, suppressors help to preserve the hearing of recreational shooters, hunters, and hunting dogs around the world. Even the most effective suppressors, on the smallest and quietest calibers (.22 LR) reduce the peak sound level of a gunshot to between 110 – 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.

From a hearing conservation perspective, according to Dr. William W. Clark, the current Director of the Washington University School of Medicine’s Program in Audiology and Communication Sciences, “the most serious threat to hearing comes from recreational hunting or target shooting”.1 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.2,3 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.4

In a 2011 study, the Centers for Disease Control and Prevention (CDC) stated, “the 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. However, some states do not permit civilians to use suppressors on firearms.”5 California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island currently do not allow civilians to own suppressors. Even if the Hearing Protection Act or the SHARE Act become law, suppressors will still not be legal in the eight states where they are currently prohibited.

In a similar study from 2014 on noise exposure at shooting ranges, NIOSH recommended, “if feasible and legally permissible, attach noise suppressors to firearms to reduce peak sound pressure levels.”6

In March, 2017, the National Hearing Conservation Association’s Task Force on Prevention of Noise-Induced Hearing Loss from Firearm Noise stated that “using firearms equipped with suppressors” is one of “several strategies [that] can be employed to reduce the risk of acquiring NIHL and associated tinnitus from firearm noise exposure.”7

Most hunters do not wear hearing protection in the field because they want to hear their surroundings. The trouble is, exposure to even a single unsuppressed gunshot can, and often does, lead to permanent hearing damage. Suppressors allow hunters to maintain full situational awareness, while still protecting their hearing. The result is a safer hunting experience for the hunter, and for those nearby.


As urban developments advance into rural areas, shooting ranges and hunting preserves across the country are being closed due to noise complaints. Although it can still be heard, suppressed gunfire helps mitigate noise complaints from those who live near shooting ranges and hunting land.


One of the most common problems for shooters is decreased accuracy caused by flinching in anticipation of the firearms discharge and recoil. By containing the explosion of the gunpowder at the muzzle, suppressors reduce recoil, and help decrease muzzle flinch. These benefits lead to improved accuracy, better shot placement, and more humane hunts.

How To Purchase A Suppressor

In order to purchase a suppressor from your dealer, you must be at least 21 years of age, a resident of the U.S. residing in one of the 42 states that currently allow civilian ownership of suppressors, and be legally eligible to purchase a firearm. Once you are ready to purchase your suppressor, you will submit the following forms and information to the ATF, and your local CLEO, varying slightly depending upon your method of purchase.

Send to ATF
      ATF Form 4 (in duplicate)
with Passport Photos
with FBI FD-258 Fingerprint Cards
with ATF Form 5320.23  – NFA Responsible Person Questionnaire
with a copy of trust documents or LLC's articles of incorporation
with $200 Transfer Tax per suppressor
Send CLEO Notification
      with copy of ATF Form 4
with copy of ATF Form 5320.23  from all Responsible Persons
Wait (way too long) for ATF Approval
