CMMG ZEROED Enhanced Lower Parts Kit MK3 Gun Builder Kit - AR-10/.308 Win

The CMMG ZEROED Enhanced Lower Parts Kit, Mk3 Gunbuilder's Kit is a curated, USA-made small-parts package designed to assemble a CMMG Mk3 / AR-10-pattern lower chambered in .308 Winchester. Every spring, detent, pin, and control needed to bring an AR-10 lower to life is included in convenient color-coded packets so the builder can quickly identify each component at the bench.

The Gunbuilder's Kit configuration is intended for builders who plan to supply their own Trigger Guard, Fire Control Group, and Pistol Grip - the three components most commonly upgraded with aftermarket parts. The kit delivers the remaining essential lower internals so you are not paying for components you intend to swap out, while still getting the precision CMMG ZEROED fit and finish on every spring, detent, pin, and control.

Engineered specifically for the CMMG Mk3 / DPMS Gen 1 high-pattern AR-10 lower pattern, this kit is the right starting point for a custom Mk3 build or a fresh lower assembly. As with the rest of the CMMG ZEROED line, all parts are made in the USA to CMMG's quality standards.

Your purchase includes:

• CMMG ZEROED Enhanced Lower Parts Kit, Mk3 - Gunbuilder's Kit configuration
• Springs, detents, pins, and controls for one AR-10 (Mk3) lower
• Color-coded packaging for easy bench identification

Note: Trigger Guard, Fire Control Group, and Pistol Grip are not included and are sold separately.
