The statute in practice
Connecticut section 53-206g defines a rate-of-fire enhancement to include a binary trigger system by treating trigger pull and reset as a single operation, and it reaches manufacture, sale, transfer, purchase, possession, and use. Public Act 18-29 created that definition effective October 1, 2018.
Timeline
What it means for you
Section 53-206g contains narrow timing provisions for specified pre-2019 possessors, newcomers, and deployed service members; those provisions should be read from the current statute before relying on a possession deadline.
Federal law
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.
