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

The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 represents a significant engineering evolution from Rare Breed. This third-generation forced reset trigger system is designed for the discerning shooter who demands precise control over cyclic rate without sacrificing the tactile feedback of a single-stage pull. Built around a proprietary flat bow design, the FRT-15L3 reduces over-travel and provides a consistent break point, offering a distinct mechanical advantage over standard mil-spec triggers. Each unit is machined from hardened tool steel and phosphate finished for corrosion resistance, ensuring long-term reliability under high-volume firing schedules.

Overview

The FRT-15L3 (Flat) Single-Stage (3-Position) forced reset trigger for the AR-15 is a direct drop-in replacement for all standard AR-15/M16 pattern lower receivers. Unlike binary or fully automatic systems, this trigger operates through a forced reset mechanism that physically returns the trigger shoe to the forward position after each shot, enabling rapid follow-up shots while maintaining semi-automatic function. The three-position safety selector allows the operator to choose between safe, semi-automatic, and the forced reset mode, providing tactical flexibility without modifying the lower receiver. Rare Breed has refined the engagement geometry to minimize trigger bounce and ensure consistent sear engagement across temperature extremes.

Features & Specs

This trigger system is manufactured to exacting tolerances by Rare Breed Firearms, a leader in precision trigger technology. The FRT-15L3 (Flat) Single-Stage (3-Position) forced reset trigger for the AR-15 includes the following design specifications:

• Single-stage trigger pull weight: factory set at 4.5 to 5.5 pounds with consistent over-travel stop; flat trigger shoe measures 0.220 inches wide with serrated face for positive finger placement
• Three-position selector: position 1 (safe) blocks hammer and trigger movement; position 2 (semi-automatic) standard single-shot per trigger pull; position 3 (forced reset) enables rapid reset cycling with each trigger release
• Drop-in cassette design: includes pre-assembled housing, hammer, trigger, disconnector, and selector; no trigger guard modifications required; compatible with all mil-spec AR-15 lower receivers

Additional specifications include a hammer weight of 2.8 ounces for reliable primer ignition, a nickel-Teflon coated sear surface to reduce friction and wear, and a full-length guide rod system that prevents sear tilt during rapid cycling. The flat trigger profile reduces the distance between the trigger face and the grip, improving ergonomics for shooters with shorter finger reach.

Who It’s For

The FRT-15L3 (Flat) Single-Stage (3-Position) forced reset trigger for the AR-15 is engineered for competitive shooters, firearms instructors, and experienced enthusiasts who require a repeatable, high-speed trigger system without compromising safety. This product is not intended for casual plinkers or first-time AR-15 builders due to the specific training required to safely operate the forced reset mode. It is best suited for users who understand the mechanical function of forced reset triggers and have experience with high-round-count training. The flat shoe design specifically benefits shooters who prefer a consistent trigger finger placement and reduced pull weight variation during rapid strings of fire. Law enforcement and military personnel may find utility in training applications where simulating cyclic rate is beneficial, though this trigger is not authorized for use in automatic weapons.
