The legality of acquiring noise suppression devices for firearms in Washington State is a complex issue governed by both federal and state regulations. These devices, often referred to as silencers, are regulated under the National Firearms Act of 1934 and require a prospective owner to complete a Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Form 4 application, undergo a background check, and pay a $200 tax stamp. Furthermore, Washington State law adds its own layer of regulation, requiring purchasers to possess a valid concealed pistol license.
The ability to reduce the sound signature of a firearm offers several potential advantages. Noise reduction can protect the hearing of shooters and those nearby, and can also diminish noise pollution in shooting areas. Historically, the regulation of these devices stemmed from concerns about their potential misuse in criminal activities. Understanding the applicable regulations is essential for anyone considering ownership in Washington State.
