Are Binary Triggers Legal in Arizona?

Arizona's ATF compendium directs readers to section 13-3102 for misconduct involving weapons and section 13-3108 for statewide firearms preemption. Neither entry creates a binary-trigger category; the relevant technical question remains whether the installed mechanism meets a separately defined prohibited-weapon or automatic-fire term.

Binary triggers are legal under federal law and are not machine guns under 26 U.S.C. § 5845(b); ATF treats the trigger pull and the trigger release as two separate functions of the trigger, so one round is fired per function. Cargill v. Garland (2024) concerned bump stocks, not binary triggers, and does not change this.

Scope: Binary triggers (Franklin Armory BFSIII and similar): fire one round on trigger pull and one on release. Forced reset triggers are a separate class.
