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 precision-engineered evolution in trigger system mechanics. Manufactured by Rare Breed, this unit employs a forced-reset function that requires the shooter to maintain forward pressure on the trigger shoe after each shot, allowing the trigger to reset under spring tension without the need for a traditional sear-disconnect cycle. Designed specifically for the AR-15 platform, this three-position selector variant provides a distinct mechanical experience suited for controlled, high-volume firing applications. The flat-faced trigger shoe reduces overall trigger reach and promotes consistent finger placement, improving shot-to-shot repeatability under rapid manipulation.

Overview

The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is a drop-in trigger group that replaces the factory fire control components in standard mil-spec lower receivers. Rare Breed has engineered this system to operate through a cam-driven forced-reset mechanism that physically returns the trigger forward after each discharge, independent of the shooter’s finger motion. This design eliminates the need for a conventional trigger reset spring, enabling a faster cyclic rate while maintaining single-shot functionality per trigger pull. The flat trigger profile reduces overall trigger travel and provides a consistent, repeatable pull weight across all positions. This unit is manufactured from heat-treated steel components with a corrosion-resistant finish to withstand extended use and environmental exposure.

Features & Specs

• Mechanical Operation: Forced-reset design uses a cam-and-slider system to physically return the trigger shoe forward after each firing cycle. The three-position safety selector provides safe, semi-automatic (normal reset), and forced-reset fire modes, allowing the user to select between standard single-shot operation and the forced-reset function depending on range or training requirements.
• Trigger Geometry: Flat trigger shoe with a 0.25-inch reduction in overall trigger reach compared to standard curved triggers. The single-stage design delivers a consistent 4.5 to 5.5-pound pull weight with minimal overtravel. The trigger break is crisp with no creep, and the forced-reset cycle resets approximately 0.10 inches forward of the break point.
• Material and Compatibility: Constructed from 4140 steel with a black nitride finish for corrosion resistance and reduced friction. Drop-in design fits all mil-spec AR-15 lower receivers without modification. Includes all necessary pins and springs. Does not require a specialized hammer or carrier. Compatible with standard AR-15 bolt carrier groups, though Rare Breed recommends a standard-weight carrier for optimal function.

Who It’s For

The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is designed for experienced AR-15 owners who understand the mechanical operation of forced-reset trigger systems. This product is intended for range use, training drills, and controlled fire-rate practice where the shooter must maintain active trigger control. It is not a binary or automatic trigger system; each discharge requires a distinct trigger pull, followed by the shooter allowing the trigger to reset under the forced-reset mechanism. Users should have familiarity with AR-15 trigger installation and function testing. This trigger is not recommended for new shooters or those unfamiliar with forced-reset mechanics.
