This is not a gimmick; it is a purpose-built, single-stage trigger system designed for shooters who want a predictable, crisp break with the unique forced-reset functionality. The flat trigger shoe gives you a consistent finger placement, which helps with recoil management and rapid follow-ups. Whether you are a competitive shooter or a dedicated enthusiast, this trigger offers a distinct mechanical advantage without sacrificing safety or reliability.

Overview

The FRT-15L3 (Flat) builds on Rare Breed’s reputation for pushing the boundaries of trigger design. It is a three-position trigger that includes a safe position, a semi-automatic position, and a forced-reset position. In the forced-reset mode, the trigger resets forward under spring tension as the bolt cycles, allowing for faster, more controlled shooting. The flat face reduces creep and provides a consistent pull every time. This is a drop-in replacement for standard AR-15 lower receivers, meaning you can install it with basic tools and no permanent modifications to your rifle.
