The Rare Breed FRT-15 E3 is a forced reset trigger designed for AR-15/M4 pattern rifles. Manufactured from 4140 steel with a black nitride finish, this trigger group uses a proprietary sear geometry to achieve a unique, rapid-fire function. It is a complete drop-in cassette unit compatible with mil-spec AR-15 lower receivers, offering a distinct mechanical alternative to a standard semi-auto trigger.

The FRT-15’s value is in its unique mechanical operation. Unlike binary triggers, it uses a forced-reset sear that trips the hammer upon release, then immediately resets the trigger as long as forward pressure is maintained. This allows for a high rate of fire with precise control over each shot. Builders seeking a specialized, mechanically distinct trigger system for their AR-15 will find this a notable component.
