CMMG ZEROED Enhanced Lower Parts Kit Mk3 AR-10/LR-308

The CMMG ZEROED Enhanced Lower Parts Kit, Mk3 is a premium upgraded AR-10 lower parts kit drawn from CMMG's ZEROED component line, designed to finish out a stripped AR-10 / LR-308 lower with mil-spec quality controls and CMMG's own upgraded drop-in internals. Every small part in the kit is built to meet or exceed mil-spec tolerances, giving builders a turnkey set of internals to complete a custom big-bore AR build without piecing together parts from a dozen different bags.

This Mk3 version of the ZEROED lower parts kit is purpose-built for CMMG's AR-10 / Mk3 platform and is designed to work with lowers using the Gen 1 DPMS High-Pattern used on LR-308-pattern rifles. Note that this kit is not compatible with the AR-15 / Mk4 platform - the AR-15 and AR-10 use different lower receiver patterns. At the heart of the kit is CMMG's signature ZEROED Drop-In Trigger paired with a smooth, ergonomic ZEROED Pistol Grip, both a clear step up from the plain mil-spec components most kits include. The kit is rounded out with five color-coded packets of installation hardware, springs, pins, and detents so every piece needed to complete the lower is in the box.

Whether you are finishing a stripped AR-10 lower, completing a custom .308 Winchester build, or replacing worn internals on a duty rifle, the ZEROED Enhanced Lower Parts Kit Mk3 delivers a cohesive matched set of components from a single trusted brand. This is new commercial production - a small-parts lower build kit only. No stripped lower, frame, or receiver is included.
