CMMG ZEROED LPK MK3 – Lower Parts Kit for .308 AR Builds

The CMMG ZEROED LPK MK3 is a complete lower parts kit engineered for builders assembling .308 AR-platform rifles. This kit includes all the small parts needed to finish a stripped MK3 lower receiver—trigger assembly, hammer, disconnector, selector, pins, springs, detents, and grip hardware. It provides a functional, no-frills foundation for shooters who want a reliable base before upgrading to aftermarket triggers or controls.

Manufactured from mil-spec steel and polymer components with a black oxide finish on metal parts. This is a drop-in kit for experienced builders familiar with AR lower assembly; proper punches, a hammer, and attention to detail are required. The kit does not include a pistol grip, stock, or buffer assembly.
