THE ROLE OF SUPPRESSORS
By definition, the primary role of a suppressor is to reduce the overall sound signature of the host firearm to hearing safe levels. They do so by trapping the expanding gasses at the muzzle and allowing them to slowly cool, in a similar fashion to car mufflers. Their muffling capabilities intrinsically make them a hearing protection device for both the shooter and those around them.
SUPPRESSOR LEGALITY AND OWNERSHIP
Suppressors are regulated under the National Firearms Act (NFA) of 1934, which is a branch of the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE). To legally purchase or possess a suppressor you must:
- Be at least 21 years of age to purchase a suppressor from a dealer.
- 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).
- 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).
- Be a resident of the United States.
- Be legally eligible to purchase a firearm.
- Pass a BATFE background check with a typical process time of 60-120 days.
- Pay a one time $200 Transfer Tax.
- Reside in one of the 39 states that currently allows civilian ownership of suppressors.
Benefits of Suppressors
According to OSHA, the threshold for a hearing safe impulse noise is 140 dB. Without hearing protection, exposure to any impulse noise over 140dB causes varying degrees of permanent noise induced hearing loss, which can also lead to tinnitus. Most well engineered suppressors take the dB level of their host firearm below 140 dB, making those suppressors effective primary hearing safety devices.
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 at the muzzle, reducing recoil, and decreasing muzzle flip, suppressorsdramatically increase accuracy, especially among new and inexperienced shooters.
BENEFITS OF SILENCERS
Because of the inherent decrease in dB levels, the use of suppressors increases situational awareness, and allows for easier communication.
