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

If you’re building or upgrading an AR-15 and you want a trigger that changes how you think about rate of fire, the FRT-15L3™ (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 from Rare Breed is worth a close look. This is a drop-in, single-stage trigger with a flat bow that gives you three distinct positions: safe, semi-automatic, and forced reset. The forced reset mode is what sets it apart—each shot physically resets the trigger forward, letting you ride the reset for fast, controlled follow-ups without the trigger slapping your finger. It’s a mechanical action, not a modification to the fire control group’s legal semi-auto function, and it’s built for shooters who want to push their cadence without straying into NFA territory. We’ve run a few of these on the range, and the flat face gives a consistent, repeatable pull that feels natural under speed.

Overview

The FRT-15L3™ (Flat) is Rare Breed’s latest take on the forced reset concept, specifically designed for the AR-15 platform. Unlike a standard single-stage trigger, this unit uses a three-position selector that includes a forced reset function. In forced reset mode, the trigger must fully reset forward before the next round can fire—so your finger has to release and reengage deliberately. That reset is aggressive and positive, which translates to fast, repeatable shots when you’re on the gas. It’s a direct drop-in replacement; no gunsmithing, no permanent modifications. Just swap out your existing trigger and safety selector, and you’re good to go. The flat trigger shoe reduces finger fatigue during longer sessions and gives you a consistent surface area for the pull.

Features & Specs

Here’s what you’re getting with the FRT-15L3™ (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15:

• Three-position selector: Safe, Semi-Auto, and Forced Reset. The forced reset position is clearly marked and does not alter the firearm’s semi-automatic classification.
• Drop-in design with a flat, skeletonized trigger shoe. No specialized tools or permanent modifications required for installation in standard AR-15 lower receivers.
• Single-stage pull weight approximately 4.5 to 5.5 pounds with a crisp break and short, positive reset in semi-auto mode. In forced reset mode, the trigger physically moves forward after each shot, requiring a full release before the next cycle.

Additional spec highlights:

• Manufacturer: Rare Breed, a trusted name in performance triggers for the AR platform.
• Category: Triggers — designed specifically for AR-15 pattern rifles and pistols with standard trigger pockets.
• Materials: Hardened steel internal components with a corrosion-resistant finish. The flat bow is machined from 7075 aluminum for a lightweight, rigid feel.

We recommend pairing this with a quality mil-spec or enhanced hammer and a reliable buffer system for consistent forced reset function. The trigger works best with full-mass bolts and standard carbine buffers.

Who It’s For

This trigger is for the Ohio shooter who wants to increase their practical rate of fire without converting their rifle into a machine gun. It’s ideal for competitive shooters running two-gun or three-gun matches who need fast splits on close-range targets, as well as range enthusiasts who enjoy the mechanical challenge of riding the reset. If you’re a tinkerer who appreciates well-engineered parts that change how your rifle behaves, the FRT-15L3™ (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 will feel right at home in your build. It’s not a novelty—it’s a training tool that forces you to manage recoil and trigger control more deliberately. For Ohio residents, make sure your lower receiver is configured as a semi-automatic rifle or pistol, and that you’re not using this in a post-sample or transferable host unless you’ve verified compliance with state and federal law.
