Washington Suppressors & Silencers Laws (2026)
Conditional: Suppressors are legal in Washington once they are registered with the federal government.
Suppressors are legal in Washington once they are registered with the federal government. RCW 9.41.250 criminalizes only the use of an unregistered suppressor. Washington's hunting rules (WAC 220-414) contain no suppressor prohibition, so hunting with a registered suppressor is allowed.

Suppressors are legal in Idaho, which has no statute banning civilian possession, and Fish and Game imposes no state restriction, so suppressors are legal for hunting all species. You need the federal ATF tax stamp under the National Firearms Act (NFA).

- OregonConditional
Suppressors are legal in Oregon once they are registered with the federal government. ORS 166.272 makes possessing a silencer a Class B felony unless it is registered under federal law, and that registration under the National Firearms Act (NFA) is a complete affirmative defense. You complete the process with an ATF Form 4 and the $200 stamp.
