This complete AR-15 lower parts kit has everything you need to finish a mil-spec dimension lower receiver: the fire control group, the controls, pins, detents, springs, the trigger guard and an A2 pistol grip. Each kit is guaranteed to fit a mil-spec lower.

The kit uses no foreign-made parts, no polymer parts and no MIM parts, and it is 100% USA made. Parts carry a phosphate finish. Use it to build out a stripped lower, or keep it on the bench as a full set of spares for an existing rifle.
