Enhanced Reset Trigger – Rare Breed FRT 15 E3

The Enhanced Reset Trigger – Rare Breed FRT 15 E3 represents a precision-engineered trigger system designed for the discerning AR-15 platform user. Manufactured by Rare Breed, this trigger utilizes a forced reset mechanism that allows the shooter to achieve rapid, controlled follow-up shots while maintaining a semi-automatic classification. Unlike binary triggers or standard drop-in units, the FRT-15 E3 employs a unique cam-and-lever system that resets the trigger forward immediately after each shot, requiring the shooter to release and re-engage the trigger for each round. This design delivers a distinct tactile experience that combines speed with deliberate trigger discipline, making it a category-defining component in the triggers market.

Overview

The Rare Breed FRT-15 E3 is the third-generation evolution of the original Forced Reset Trigger platform. This enhanced reset trigger – Rare Breed FRT 15 E3 incorporates a redesigned hammer, sear, and trigger housing to improve durability and reliability across varied ammunition types. The E3 variant features an optimized cam profile that reduces friction points, resulting in a smoother reset feel compared to previous generations. The trigger housing is machined from 7075-T6 aluminum with a hard-coat anodized finish, while the internal steel components receive a QPQ nitride treatment for corrosion resistance and wear longevity. The unit is self-contained and requires no modifications to the lower receiver beyond standard trigger installation procedures.

Who It’s For

This enhanced reset trigger – Rare Breed FRT 15 E3 is designed for experienced AR-15 builders and shooters who prioritize high-speed follow-up shot capability without sacrificing the semi-automatic legal classification. It suits competitive shooters in divisions that permit forced reset triggers, as well as enthusiasts building dedicated range rifles for controlled rapid-fire practice. The trigger is not intended for defensive or duty use due to the unique manual of arms required; shooters must maintain positive finger control and cannot simply hold the trigger rearward for continuous fire. This product is for users who understand the mechanical operation of forced reset systems and have experience with aftermarket trigger installation.
