Does Washington Have an Assault Weapons Ban?

Washington's RCW 9.41.010 definition combines a long named-firearm list with feature tests and separate fixed-magazine and overall-length branches. For a semiautomatic centerfire rifle with a detachable magazine, one listed feature is enough.

RCW 9.41.390 addresses manufacture, importation, distribution, sale, and offers for sale. It provides limited exceptions for inheritance, out-of-state disposition, dealer repair, and specified government or law-enforcement conduct.

There has been no federal assault weapons ban since the 1994 ban expired in 2004; no feature restrictions apply federally to semi-automatic rifles or pistols. The 2023 ATF pistol-brace rule was vacated nationwide and is not enforced, but federal SBR classification for a brace-equipped firearm still turns on whether the specific weapon is designed and intended to be fired from the shoulder. Cargill v. Garland (2024) made bump stocks federally legal. Feature bans are entirely a matter of state law.

Federal baseline verified 2026-07-31. Scope: State laws restricting semi-automatic rifles, pistols, and shotguns by configuration features: threaded barrels, pistol grips, folding or telescoping stocks, flash suppressors, forward grips, and similar. Magazine capacity limits are tracked as a separate class.
