The skeletonized straight shoe single-stage trigger is steel with material removed from the trigger body for weight reduction while maintaining the straight flat trigger face geometry. The steel hammer and disconnector complete the fire control group. The kit includes a safety selector, bolt catch, magazine catch assembly, pivot pin, takedown pin, hammer and trigger pins, detents and springs, and an A2-style ergonomic pistol grip in black with grip hardware.

Mil-Spec Buffer Assembly

The buffer assembly includes a Mil-Spec heavy-duty 6-position carbine receiver extension compatible with standard Mil-Spec AR-15 stocks and braces. The standard 3 oz carbine buffer has an aluminum body with steel weights. A USA-made standard carbine recoil spring, an AR-15 M16 Mil-Spec end plate, and an AR-15 carbine castle nut complete the rear hardware. Stock or brace selection remains with the buyer.
