FRT-15L3 Single-Stage (3-Position) Forced Reset Trigger for the AR-15

The FRT-15L3 Single-Stage (3-Position) Forced Reset Trigger for the AR-15 represents a significant engineering milestone from Rare Breed, designed for shooters who demand precise control and a unique mechanical operating cycle. This third-generation forced reset trigger system delivers a distinct single-stage pull with a three-position selector, allowing the operator to choose between safe, semi-automatic, and the forced reset binary-like function. As a direct drop-in unit for standard AR-15 lower receivers, the FRT-15L3 eliminates the need for modification or specialized tools, making it a practical upgrade for any serious rifle build.

Overview

The Rare Breed FRT-15L3 is a single-stage trigger that uses a mechanical forced reset mechanism to return the trigger forward after each shot, enabling a rapid firing cycle while maintaining full compliance with federal regulations. Unlike traditional binary triggers, the FRT-15L3 requires the shooter to hold the trigger and then release it to reset, giving the operator direct control over the rate of fire. The three-position safety selector provides clear markings for safe, semi-automatic, and the forced reset position. This trigger is engineered for AR-15 platforms chambered in 5.56 NATO and .223 Remington, and it fits both mil-spec and many aftermarket lowers without additional fitting.

Features & Specs

The FRT-15L3 Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is built from precision-machined steel components with a corrosion-resistant finish. The single-stage pull weight is factory-set to approximately 4.5 to 5.5 pounds, providing a crisp break with minimal overtravel. The forced reset function is mechanically actuated by the bolt carrier group, ensuring reliable cycling across a wide range of ammunition types and buffer weights.
