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

If you have been looking for a trigger that changes how you think about your AR-15’s fire control group, the FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is where your search ends. Built by Rare Breed, this trigger is a direct result of listening to shooters who wanted a flat-faced option in the forced reset category. It offers the same reliable, three-position functionality as its curved counterpart, but with a flat trigger shoe that many competitive and tactical shooters prefer for consistent finger placement.

This isn’t a gimmick. The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 uses a mechanical forced-reset design that resets the trigger forward as the bolt cycles, allowing for rapid follow-up shots. It is a single-stage trigger with a clean, crisp break, and the three-position selector gives you safe, semi-automatic, and the forced-reset mode. Rare Breed designed this unit to drop into standard mil-spec lower receivers with minimal fitting, making it a straightforward upgrade for anyone who wants to push their AR-15’s performance.

Overview

The Rare Breed FRT-15L3 is the flat shoe version of the original FRT-15 forced reset trigger. It is a single-stage, three-position trigger group that fits AR-15 pattern rifles. The “L3” designation indicates the flat shoe, which provides a wider, more consistent surface for your trigger finger. This trigger is manufactured in the United States by Rare Breed, a company known for pushing the boundaries of AR-15 fire control systems. It is important to understand that this is a forced reset trigger, not a binary or full-auto trigger. The trigger resets forward automatically after each shot, but you must release it fully before the next shot can occur.
