CMMG Zeroed Lower Parts Kit AR-15 Gunbuilders Kit - Black Matte

Finish out your next AR-15 build with the CMMG ZEROED Lower Parts Kit, packaged in their Gunbuilders Kit configuration (MPN 55CA6BA). This LPK bundles the core small parts needed to bring a stripped AR-15 lower receiver to life: the trigger guard, fire control group, and pistol grip, all drawn from CMMG's signature ZEROED line.

CMMG built the ZEROED line for builders who want clean, functional hardware without paying premium-kit prices. Every component in the Gunbuilders Kit is finished in a low-glare black matte that pairs cleanly with standard AR-15 lowers and blends with most anodized or Cerakoted color schemes.

Whether you're assembling a complete rifle from a stripped lower, refreshing an existing build, or replacing worn hardware, this LPK delivers the major lower-receiver interfaces - trigger guard, fire control group, and pistol grip - in a single boxed set from one of the most respected names in AR-15 manufacturing.
