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 iteration of Rare Breed’s precision-engineered forced reset trigger system. Designed for the discerning AR-15 owner who demands consistent, repeatable trigger resets under high-speed manipulation, this flat-faced, single-stage unit incorporates a three-position selector for enhanced operational control. Unlike binary or standard mil-spec triggers, the FRT-15L3 leverages a mechanical forced reset mechanism that physically returns the trigger forward after each shot, enabling a rapid follow-up cadence while maintaining semi-automatic compliance in all three selector positions.

Overview

The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is purpose-built for shooters who prioritize speed, consistency, and tactile feedback. Rare Breed has refined the forced reset geometry to reduce over-travel and ensure a crisp, defined wall at the break point. The flat trigger shoe provides a consistent finger placement surface, minimizing lateral movement during rapid fire strings. This trigger is engineered for drop-in installation into standard AR-15 lower receivers without permanent modification, making it a straightforward upgrade for both new builds and existing rifles. The three-position selector allows for safe, semi-automatic, and the forced reset mode, each clearly defined by positive detent engagement.

Features & Specs

• Mechanical Forced Reset System: The FRT-15L3 utilizes a patented internal cam and sear geometry that physically pushes the trigger shoe forward after each hammer fall. This eliminates the need for the shooter to manually release the trigger between shots, resulting in a significantly faster cyclic rate while the trigger remains in a single-stage configuration. The break weight is calibrated to 4.5 to 5.0 pounds with minimal creep, providing a predictable, repeatable pull.
• Flat Trigger Shoe with Serrated Face: Machined from 4140 steel and finished with a corrosion-resistant nitride coating, the flat shoe reduces perceived trigger reach and offers a broad, stable surface for consistent finger placement. The vertical serrations on the face improve positive engagement in adverse conditions such as rain, gloves, or rapid movement.
• Three-Position Selector: The trigger includes a hardened steel selector with three distinct positions: Safe (blocked), Semi-Automatic (standard single-shot per trigger pull), and Forced Reset Mode (mechanical reset engaged). Each position features an audible and tactile detent click, ensuring the operator can confirm configuration without breaking sight alignment.
• Drop-In Design with Mil-Spec Compatibility: The FRT-15L3 uses a drop-in cassette housing constructed from heat-treated aluminum and steel components. It fits all standard mil-spec AR-15 lower receivers. No trigger guard modification, filing, or permanent alteration is required.

Who It’s For

This trigger is intended for experienced AR-15 owners who understand the mechanical operation of forced reset systems and are compliant with all applicable federal, state, and local laws. It is suited for competitive shooters in divisions that allow forced reset triggers, training applications requiring high-volume fire, and enthusiasts who want the fastest possible semi-automatic trigger cycle without stepping into full-automatic territory. The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is not recommended for first-time AR builders or those unfamiliar with trigger maintenance and proper safety protocols. Users should verify that the forced reset mechanism is legal in their jurisdiction before purchase.
