CMMG ZEROED Enhanced Lower Parts Kit AR-15

This is CMMG's ZEROED Enhanced kit for an AR-15 lower, and the ambidextrous parts are what set it apart from a standard parts bag. The safety selector is adjustable between a 60 and 90 degree throw, the magazine catch and release are ambidextrous, and the pivot and takedown pins are the heavy duty version rather than the plain pins that tend to walk under recoil.

Everything else a bare receiver needs is in the bag: bolt catch plunger, spring and roll pin, trigger and hammer retaining pins, detents and springs, and the buffer retainer with its spring. Parts come in color coded packets so nothing gets lost mid assembly. The fire control group, trigger guard, and pistol grip are not included.
