Are Binary Triggers Legal in Delaware?

Statute-cited, last verified 2026-07-10

Banned

No. Prohibited as a rapid fire device; manufacture, sale, transfer, purchase, and possession are barred.

Controlling law: 11 Del. C. § 1444

Litigation Status and Details

Delaware's rapid fire device definition (a device that increases the rate of fire beyond what is possible unassisted) reaches binary triggers; classed with destructive weapons (class E felony).

Federal baseline

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.
