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

If you have been looking for a trigger that blends rapid-fire capability with the control of a single-stage design, the Rare Breed FRT-15L3 is worth your attention. This is the latest generation of the forced reset concept, refined for reliability and smoother operation. Unlike standard triggers that rely on a binary or full-auto sear, the FRT-15L3 uses a mechanical forced reset that returns the trigger forward immediately after each shot, allowing you to pull again faster than a conventional trigger. It is a purpose-built component for the AR-15 platform that gives you a unique shooting experience without modifying your lower receiver.

Overview

The FRT-15L3 is a single-stage, three-position forced reset trigger designed specifically for the AR-15. It replaces your existing trigger group and works with standard mil-spec fire control pockets. The “L3” designation indicates the third iteration of Rare Breed’s forced reset technology, featuring improved geometry and a more positive reset feel. This trigger is not a binary trigger and it is not a machine gun conversion device. It is a semi-automatic trigger that uses mechanical leverage to reset the trigger shoe forward under recoil, enabling a faster follow-up shot. The three-position selector offers safe, semi-automatic, and the forced reset mode. It is a drop-in assembly that requires no permanent modification to your rifle.

Features & Specs

• Single-stage design with a crisp 4.5-pound pull weight and a short, tactile reset that allows for rapid, controlled fire in the forced reset position.
• Three-position selector: Safe, Semi (standard semi-auto fire), and FRT (forced reset mode) for an accelerated firing cycle while remaining legally semi-automatic.
• Manufactured by Rare Breed, a US-based company known for advanced trigger systems. This unit is machined from heat-treated steel and aluminum with a phosphate finish for durability.

The FRT-15L3 is a direct drop-in replacement for AR-15 lower receivers that accept standard mil-spec trigger groups. No additional parts are required. It includes the trigger shoe, hammer, disconnector, sear, selector, and all necessary springs and pins. The forced reset mechanism is self-contained within the trigger group, meaning you do not need to modify your bolt carrier or buffer system. It has been tested with a variety of ammunition types and upper receiver configurations, though performance may vary with heavy buffers or weak springs. For best results, use a standard carbine buffer and a quality semi-auto bolt carrier group.

Who It’s For

This trigger is for experienced AR-15 owners who want to push their shooting speed without going down the NFA route. It is suited for competitive shooters in divisions that allow forced reset triggers, for recreational shooters who enjoy the challenge of fast follow-up shots, and for anyone who wants to explore the mechanical innovation behind the FRT design. It is not a beginner trigger; you should be comfortable with your rifle’s manual of arms and understand the legal boundaries of semi-automatic fire. The FRT-15L3 works best on a rifle that is already reliable in semi-auto mode. If your gun runs well with a standard trigger, it will run well with this one. Keep in mind that the forced reset mode requires a firm, consistent grip and a stable shooting platform to get the most out of the rapid cycling.

Shipping & FFL

Because the FRT-15L3 is a trigger assembly and not a firearm frame or receiver, it ships directly to your door with no FFL transfer required. However, federal law restricts this trigger to use in semi-automatic firearms only. It is your responsibility to ensure that installation and use comply with all applicable federal, state, and local laws. Some states and municipalities have enacted restrictions on forced reset triggers. Before ordering, verify that this product is legal in your jurisdiction. We recommend consulting with a local firearms attorney if you have any questions. This product is intended for lawful purposes only. By purchasing, you acknowledge that you are not prohibited from owning firearm parts and that you will use the trigger in compliance with all laws.
