The Rare Breed Triggers FRT-15 is a forced-reset trigger system for the AR-15 platform. Manufactured by Rare Breed Triggers, it utilizes a proprietary internal mechanism to achieve a uniquely rapid and consistent reset. This drop-in trigger group is constructed from heat-treated steel and aluminum with a black nitride finish, designed for compatibility with mil-spec AR-15 lower receivers chambered in 5.56/.223.
Key Features
- Forced Reset Trigger (FRT) mechanism eliminates the need for manual trigger finger release for follow-up shots.
- Delivers a consistent, rapid rate of fire comparable to a binary trigger, but with a distinct mechanical operation.
- Drop-in design with anti-walk pins for straightforward installation in mil-spec lowers.
- Heat-treated 4140 steel internal components and 6061-T6 aluminum housing for durability.
- Black nitride finish provides corrosion resistance and a smooth bearing surface.

As a mechanical trigger, the FRT-15’s operation is distinct. The sear is forced forward to reset the trigger as bolt carrier group reciprocates, allowing for a high cyclic rate with proper technique. This makes it a subject of significant ATF scrutiny. Purchasers must verify current federal and state legality. It is a specialized component for experienced shooters focused on mechanical function and rapid-fire drills.
