About this product
The CMMG Mk3 lower receiver is the starting point for a 308 AR build. It follows the DPMS LR-308 Gen 1 high profile pattern, the most common 308 AR layout, so it works with the widest range of 308 AR parts on the market and accepts LR-308 / SR-25 pattern magazines. It is machined from billet aluminum with an integrated trigger guard and finished in Armor Black Cerakote.
The receiver comes stripped. Finish it with CMMG's Mk3 lower parts kit for a simple build, or use the ZEROED Gunbuilder's kit and a drop in AR-10 trigger for a more custom setup. Like an AR-15, it takes the same pistol grips, and a buffer tube and stock kit completes the lower.
