Suppressor Laws in Hawaii (2026): Is It Legal?
Woody's answers are based on published federal and state law. Not legal advice. Consult a licensed attorney for your specific situation.
Hawaii prohibits civilian ownership of suppressors entirely. They are banned under state law regardless of federal NFA compliance.
What This Means for You
Hawaii maintains some of the strictest suppressor laws in the nation, with a complete prohibition on civilian possession. Even if you have a federal tax stamp and NFA compliance, Hawaii state law overrides federal permissions. This puts Hawaii in a small group of states with total suppressor bans.
The Detail
Hawaii explicitly prohibits suppressors for civilian use under state law. Unlike most states that allow NFA items with proper federal registration, Hawaii has chosen to ban suppressors outright. This means that even if you complete the entire federal NFA process, pay the $200 tax stamp, and receive ATF approval, you still cannot legally possess a suppressor in Hawaii.
The state law creates a complete prohibition that supersedes federal permissions. Hawaii does not recognize out-of-state suppressor ownership either, so travelers cannot bring legally owned suppressors into the state. Law enforcement and military personnel may have different rules, but civilian possession remains prohibited across the board.
This ban extends to all types of suppressors regardless of caliber, intended use, or construction method. Whether you're considering a rimfire suppressor for target shooting or a centerfire can for hunting, Hawaii law treats them all the same. The prohibition applies to both commercially manufactured suppressors and any homemade devices that would qualify as suppressors under federal definition.
Verify current Hawaii suppressor laws through official state resources before making any decisions, as firearms laws can change. The Hawaii Attorney General's office and local law enforcement agencies can provide definitive guidance on current statutes and any potential updates to suppressor regulations.
Build Impact
If you're planning any build in Hawaii, suppressors are completely off the table regardless of your federal compliance status. You'll need to focus your build decisions on other aspects like barrel length, stock configuration, and overall rifle setup while staying within Hawaii's restrictive firearms framework.
