Are Binary Triggers Legal in Kansas?

ATF's Kansas compendium identifies section 12-16,124 as the statewide firearms-preemption provision and lists no state binary-trigger or rate-enhancement offense. A device still must be evaluated with the host firearm under Kansas's generally applicable weapons provisions rather than from a retailer's shipping list.

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.
