CMMG Zeroed Lower Parts Kit Mk3 for AR-15

The CMMG Zeroed Lower Parts Kit is a complete set of components for finishing an AR-15 lower receiver, sold as a single bundle. It is built around CMMG's Zeroed line of enhanced parts rather than standard mil-spec equivalents, giving builders upgraded controls and ergonomics.

The kit includes an extended bolt catch, an adjustable ambidextrous safety that offers 60 or 90 degree throws, and an ambidextrous magazine catch and release button. Heavy duty pivot and takedown pins with detents and springs, trigger and hammer retaining pins, and a buffer retainer with spring complete the package. The parts are finished in black to match standard AR-15 finishes.
