State Legality Matrix / Assault Weapon Feature Bans / Hawaii
Statute-cited, last verified 2026-07-10
Yes. Assault pistols only, via a two-feature test; possession, sale, and transfer of assault pistols is a class C felony. Rifles are not feature-banned. Effective 1992-06-01.
Controlling law: Haw. Rev. Stat. §§ 134-1 & 134-8
Triggering features: magazine outside grip, threaded barrel, barrel shroud.
Scope is pistols only: a semi-auto pistol taking a detachable magazine with two or more of a magazine attaching outside the grip, a threaded barrel, or a barrel shroud. Semi-auto rifles have no Hawaii feature ban; the separate over-10-round pistol-magazine ban still applies.
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 by the Fifth Circuit and is not enforced, so braced pistols are not SBRs under federal law. Cargill v. Garland (2024) made bump stocks federally legal. Feature bans are entirely a matter of state law.
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.

In a feature-ban state, swapping the pistol grip for a featureless grip is the cheapest path to a compliant rifle that keeps its detachable magazine. These grips are purpose-built for that test.
Wider fin-style featureless grip with a fuller palm shelf for shooters who want more support than the Simple grip.
Fin-style featureless grip that replaces the protruding pistol grip on a feature-restricted AR-15 build.
Billet aluminum featureless grip for California AR-15 builds that keeps a standard magazine release.
