Partisan Triggers Disruptor AR-15 FRT 3 Position Drop In Forced Reset Trigger in Green

The Partisan Triggers Disruptor is a three-position drop-in forced reset trigger for AR-15 platforms that fires one round per trigger pull. One of the standout three-position trigger options we carry, the Partisan Disruptor FRT installs as a true direct drop-in replacement — no modification, gunsmithing, or fitting — and offers Safe, Semi-Automatic, and Enhanced Semi-Automatic selector positions. It is offered in black and green finishes.

The Partisan Disruptor fires one round per trigger pull and, after the May 2025 DOJ settlement, forced reset triggers of this type are not classified as machine guns under federal law. State and local laws vary, so confirm yours before buying. You must be of legal age and eligible under federal, state, and local law to purchase.

Specifications and fitment

Direct drop-in installation

Unlike a super safety, the Partisan Disruptor is a true drop-in replacement trigger that requires no fitting or gunsmithing. It fits most AR-pattern lowers, and anti-walk pins are recommended to keep the assembly secure under repeated cycling. Match the buffer to your build: an H2 buffer at minimum (H3 recommended) for carbine extensions with 16-inch or shorter barrels, or a standard rifle buffer for 20-inch A2 stocks.

Built for control

Wear surfaces are constructed from tool steel and 4140 chromoly for strength and extended service life, and the trigger breaks in the 3.75 to 4.1 lb range for a consistent, controllable pull. The three-position selector lets you move between Safe, Semi-Automatic, and Enhanced Semi-Automatic so you can tailor how the rifle runs while keeping the dependable function expected from the forced reset triggers at FRT Triggers USA.
