The Rare Breed Triggers FRT-15 forced reset trigger system redefines semi-automatic performance for AR-15 platforms, delivering consistent rapid-fire capability while maintaining factory reliability. This isn’t a binary trigger—it’s a precision-engineered mechanical solution that maximizes your rifle’s potential within standard operating parameters.

What you get

• Rare Breed Triggers FRT-15 forced reset trigger unit (specific model varies by SKU)
• Patented forced-reset mechanism maintains semi-auto function while optimizing reset speed
• CNC-machined 4140 steel trigger and hardened tool steel disconnector
• Type III hard-coat anodized aluminum housing
• Precision coil springs with 300% duty cycle rating versus mil-spec
• Compatible with standard AR-15 fire control groups pockets

Build and finish

The FRT-15’s construction begins with stress-relieved 4140 chromoly steel for the critical trigger components, heat-treated to RC 40-44 for wear resistance without brittleness. The aluminum housing receives a military-spec Type III hard coat anodizing that withstands abrasion and chemical exposure better than standard finishes.

Tolerances are held to ±0.0005″ on all bearing surfaces, with the forced reset mechanism’s cam profile being particularly critical. The design uses a positive engagement geometry that eliminates creep while maintaining a crisp 4.5-5 lb pull weight. All springs are manufactured from chrome silicon wire with shot-peened surfaces to prevent fatigue failures.

Compatible platforms

• AR-15 pattern rifles with mil-spec fire control pockets
• Most forged and billet lowers (check clearance for oversized designs)
• Requires standard hammer/trigger pins (0.154″ diameter)
• Not compatible with drop-in cassette triggers or proprietary systems

Installation notes

Installation follows standard AR-15 trigger replacement procedures—remove the existing fire control group, insert the FRT-15 unit ensuring proper orientation of the reset mechanism, and secure with trigger pins. No modification to the lower receiver is required, though we recommend function testing before live fire.

For serious shooters who understand their platform’s mechanics, the Rare Breed FRT-15 delivers measurable performance gains without compromising reliability. This is precision engineering applied to the most critical interface between shooter and rifle—the trigger system—with all components manufactured to withstand professional use.
