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

Overview

The FRT-15L3 Single-Stage (3-Position) Forced Reset Trigger for the AR-15 represents a refined evolution of Rare Breed’s patented forced reset trigger technology. This third-generation unit integrates a three-position safety selector with a single-stage trigger pull, engineered to deliver a consistent 4.5-pound break and a positive, mechanical reset that cycles the trigger forward after each shot. Unlike binary or full-auto systems, the FRT-15L3 operates entirely within semi-automatic parameters by using the bolt carrier’s rearward travel to physically reset the trigger shoe, enabling rapid follow-up shots without modifying the firearm’s internal fire control group classification. The unit is machined from 7075-T6 aluminum housing with hardened tool steel internal components, finished with a MIL-SPEC Type III hard coat anodized surface. This FRT-15L3 Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is designed for direct drop-in installation into standard mil-spec lower receivers without requiring any permanent modifications, sear engagement adjustments, or aftermarket bolt carriers.

Features & Specs

• Three-position selector: safe, semi-automatic, and forced reset mode (3-position configuration enables legal semi-automatic function with mechanical reset assist)
• Single-stage trigger with 4.5-pound pull weight measured from first stage engagement to hammer release, using precision-ground sear surfaces with a 0.030-inch over-travel stop
• Drop-in cassette design includes pre-assembled trigger shoe, hammer, disconnector, and proprietary reset linkage; no pins, springs, or hammer adjustments required for installation

The FRT-15L3 Single-Stage (3-Position) Forced Reset Trigger for the AR-15 uses a patented cam-and-slider mechanism that interfaces with the bolt carrier’s forward movement to reset the trigger. The hammer is constructed from S7 tool steel, heat-treated to 48-52 HRC, and the trigger shoe features a 0.25-inch wide smooth curved face with an integrated trigger safety blade. The unit maintains a total fire control group height of 1.45 inches and a width of 0.98 inches, fitting all mil-spec lower receiver pockets without spacer plates. Cyclic rate is dependent on the shooter’s trigger finger return speed and the host firearm’s bolt carrier mass and buffer weight. Rare Breed specifies compatibility with carbine, mid-length, and rifle gas systems using standard-weight carriers and buffers (H1, H2, or H3 buffers may be used for tuning).

Who It’s For

This trigger is intended for experienced AR-15 builders and competitive shooters who understand the mechanical distinction between forced reset technology and automatic fire. It is suited for those who require a repeatable, single-stage trigger for controlled rapid fire strings in training drills, three-gun matches, or steel plate competitions where split times matter but regulatory compliance is non-negotiable. The FRT-15L3 Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is not recommended for first-time builders, law enforcement duty weapons, or hunting applications where a light, crisp single-stage may be preferable. Users should have familiarity with AR-15 safety selector functionality and be comfortable verifying proper hammer and disconnector engagement after installation. This trigger demands a firm, consistent grip technique to achieve the forced reset cycle; limp-wristing or loose shoulder contact may interrupt the reset sequence.

• Recommended for competitive shooters and training enthusiasts who prioritize high-round-count trigger consistency and mechanical reset reliability
• Requires a lower receiver with a standard mil-spec trigger pocket and a bolt carrier with a standard cam pin profile (M16-profile carriers are not required and will not alter function)
• Not legal for use in all jurisdictions; check local, state, and federal regulations prior to purchase or installation
