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

Developed and manufactured by Rare Breed, the FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 represents a precision-engineered evolution in fire control technology. This trigger system utilizes a three-position selector and a forced reset mechanism that physically returns the trigger forward after each shot, requiring the shooter to release and re-engage the trigger for the next cycle. Built for the AR-15 platform, the FRT-15L3 delivers consistent, repeatable performance through its flat-faced design and single-stage pull. Each unit is CNC-machined from billet steel with a Mil-Spec hardness coating, ensuring dimensional stability and resistance to wear under sustained use.

Overview

The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is a direct drop-in assembly that replaces the standard mil-spec trigger group without requiring modifications to the lower receiver. The three-position selector functions include safe, semi-automatic, and forced-reset mode. In forced-reset mode, the trigger mechanism uses stored energy from the hammer to push the trigger shoe forward after each shot, allowing the shooter to reset the trigger without fully releasing finger pressure. This system is designed for experienced shooters who understand manual trigger manipulation and mechanical function. Rare Breed manufactures each unit in the United States using domestic materials and quality control protocols.

Features & Specs

• Three-position selector: Safe, Semi-Automatic, Forced-Reset (FR) mode. The FR mode physically resets the trigger shoe forward after each firing cycle, enabling rapid follow-up shots through deliberate trigger release and re-engagement.
• Single-stage flat trigger shoe: The flat face provides consistent finger placement across the trigger surface, reducing lateral torque and improving shot-to-shot repeatability. Pull weight is factory-set at 4.5 lbs +/- 0.5 lbs with a short, tactile reset in semi-automatic mode.
• Drop-in design: No gunsmithing required. Installs directly into standard AR-15 lower receivers with a standard trigger pocket. Includes anti-walk pins to prevent trigger pin migration during operation.

Additional specifications include a CNC-machined 4140 steel hammer and trigger with a QPQ corrosion-resistant finish. The disconnector is spring-loaded with a hardened engagement surface. The FRT-15L3 is compatible with all standard AR-15 bolt carrier groups and buffer systems. This trigger is not compatible with drop-in cassette-style trigger housings or aftermarket safety selectors that do not meet mil-spec dimensions.

Who It’s For

The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is intended for competitive shooters, advanced hobbyists, and firearms enthusiasts who operate within a controlled training environment. This trigger demands a thorough understanding of manual trigger manipulation, as the forced-reset function requires the shooter to consciously release the trigger after each shot to allow the reset cycle to complete. It is not recommended for new shooters, defensive firearms, or duty use. Users must verify compliance with all applicable federal, state, and local laws regarding trigger mechanisms before purchase. This product is a mechanical device and does not alter the semi-automatic classification of the host firearm when used as designed.
