State Legality Matrix / Binary Triggers / Oregon
Statute-cited, last verified 2026-07-10
No. Expressly prohibited as a binary trigger system under the 2025 rapid fire activator ban. Effective 2025-09-26.
Controlling law: Or. Rev. Stat. § 166.352 (SB 243, 2025)
SB 243 (Community Safety Firearms Act) defines binary trigger system as a device that allows the firearm to fire both when the trigger is pulled and when released; possession is a class A misdemeanor and manufacture, sale, or transfer a class B felony, with no grandfather clause.
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.
