Washington State law permits firearm silencers, often called suppressors, but their ownership and use are strictly regulated under both state and federal law. Acquiring one involves a thorough background check through the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and adherence to the National Firearms Act (NFA). This includes submitting fingerprints, photographs, and paying a $200 tax stamp.
Noise reduction offered by these devices provides significant hearing protection for shooters and those nearby, mitigating the potential for long-term hearing damage. In specific scenarios, this noise reduction can also enhance accuracy by reducing flinching. Historically, regulations surrounding silencers stem from the NFA of 1934, enacted amidst concerns about organized crime. These regulations remain a key aspect of federal firearms law.
