Are Binary Triggers Legal in Texas?

Texas Penal Code section 46.05 addresses enumerated prohibited weapons and contains federal-registration exceptions for specified NFA items. ATF's Texas compendium does not identify a separately named binary-trigger or multiburst-trigger offense, making the actual operation and resulting firearm classification the relevant state-law facts.

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.

Federal baseline verified 2026-07-31. 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.
