Can you use a suppressor on a PCP air rifle legally?

April 5, 2026

Quick Answer

In the United States, a suppressor can be attached to a PCP air rifle but requires compliance with the National Firearms Act (NFA) and state laws. Registration with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is necessary. A tax stamp and fingerprints are also required.

Regulations and Registration

To attach a suppressor to a PCP air rifle, you must comply with the NFA and state laws. The suppressor must be registered with the ATF, and you must obtain a tax stamp. This process typically takes several months to a year. The tax stamp costs $200, and you must provide fingerprints and a background check. The registration process requires filling out Form 4 and submitting it to the ATF.

Suppressor Design and Compatibility

When selecting a suppressor for a PCP air rifle, consider the type of barrel threading and the suppressor’s design. Most PCP air rifles have a 1/2-20 or 11/16-28 thread pattern. Choose a suppressor with a compatible thread pattern to ensure a secure attachment. Look for a suppressor designed for high-pressure air rifles, as they can handle the intense pressure generated by PCP systems.

Hunting with a Suppressed PCP Air Rifle

When hunting with a suppressed PCP air rifle, consider the environment and the type of game you’re pursuing. The suppressor will reduce the noise level, making it more suitable for hunting in areas with noise restrictions. However, the reduced report may not be enough to deter larger game, such as deer. Always use ethical hunting practices, and make sure to follow local laws and regulations regarding hunting with suppressed firearms.
