Are Bump Stocks Legal in Hawaii?

BANNED: Hawaii bans bump stocks at the state level.

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

What the law says

Hawaii’s ban is codified at HRS § 134-8 (“multiburst trigger activator”).

  • Controlling law: HRS § 134-8 (“multiburst trigger activator”)
  • Enacted: 2018
  • Penalty: Felony

Hawaii bans multiburst trigger activators, a statutory definition that includes bump stocks.

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 Hawaii: 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 Hawaii?

Yes — state law bans bump-fire stocks in Hawaii, 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 Hawaii?

The statute provides for penalties including: felony. Either way, it is a criminal matter, not a fine-and-forget violation.

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

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