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 the latest evolution in forced reset trigger technology from Rare Breed. Designed for shooters who demand consistent, repeatable performance, this flat-faced trigger system delivers a crisp single-stage pull with a mechanical forced reset mechanism that returns the trigger forward under spring tension after each shot. The three-position selector allows the operator to choose between safe, semi-automatic, and forced reset modes, providing versatility for range training, competition, and tactical applications. This unit is built to MIL-SPEC dimensions and drops directly into standard AR-15 lower receivers with no modification required.

Overview

Rare Breed has engineered the FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 to meet the rigorous demands of high-volume shooters. The flat trigger shoe reduces finger slip and provides a consistent contact surface for rapid follow-up shots. Unlike traditional binary triggers, this system uses a mechanical forced reset that does not rely on bolt carrier movement to reset the sear. The result is a trigger that resets immediately after each shot, enabling faster cycling while maintaining single-shot functionality per trigger pull in forced reset mode. The housing is machined from 7075-T6 aluminum, and all internal components are heat-treated steel for longevity under sustained use.

Features & Specs

• Three-Position Selector: Safe, Semi-Automatic, and Forced Reset modes. The forced reset position mechanically pushes the trigger forward after each shot, allowing the shooter to feel a distinct reset without releasing the trigger fully.
• Flat Trigger Shoe: Machined from 6061 aluminum with a hardcoat anodized finish. The flat profile reduces trigger reach and promotes a straight-back pull for improved accuracy under rapid fire.
• Drop-In Installation: Fits standard AR-15 mil-spec lower receivers. Includes anti-walk pins and a detailed installation guide. No fitting, drilling, or permanent modification required.

Additional specifications: Single-stage pull weight of 4.5 to 5.5 pounds (factory set), nickel-Teflon coated sear engagement surfaces for reduced friction, and a stainless steel hammer pin. The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is compatible with all standard AR-15 bolt carrier groups and buffer systems. Rare Breed recommends using a standard-weight carbine buffer for optimal performance in forced reset mode.
