Are Bump Stocks Legal in Washington?

BANNED: Washington bans bump stocks at the state level.

Before you bring a bump stock into Washington, read this. State law here goes further than federal law, and the difference matters.

What the law says

Washington’s ban is codified at RCW 9.41.190.

  • Controlling law: RCW 9.41.190
  • Enacted: 2018
  • Penalty: Class C felony, up to 5 years + $10,000

Washington banned bump-fire stocks under RCW 9.41.190 in 2018.

The federal picture

In Garland v. Cargill (decided June 2024), the U.S. Supreme Court struck down the ATF rule that had reclassified bump stocks as machine guns. Since that ruling, bump stocks are legal under federal law. That does not help you in Washington: the state’s own ban operates independently of federal law and remains fully enforceable.

Frequently asked questions

Is it illegal to have a bump stock in Washington?

Yes — state law bans bump-fire stocks in Washington, and the ban has been in force since 2018. This applies regardless of the device’s federal status.

What happens if I’m caught with one in Washington?

The statute provides for penalties including: class c felony, up to 5 years + $10,000. Either way, it is a criminal matter, not a fine-and-forget violation.

I bought mine legally in another state — does that matter in Washington?

Where you bought it doesn’t change Washington law. Possession inside the state is what the statute reaches. If you move to Washington, consult an attorney about lawful disposition before you arrive.
