Color-Coded Lower Parts Kit For Easy Assembly For AR-10

The CMMG MK3/AR-10 Zeroed Lower Parts Kit is a complete package consisting of high-quality USA-made parts designed to finish off an MK3/AR10 stripped lower receiver. All parts come in convenient color-coded packets to make assembly a breeze and are designed to meet or exceed mil-spec specifications to ensure the smoothest operation possible of the AR-10 rifle.

This LPK includes the Zeroed Pistol Grip, Trigger Assembly, and a 60°/90° Adjustable Ambi Safety selector making it a great option to start your next build.

NOTE: Not all .308 lowers have the same specifications. This LPK is designed to work with CMMG lowers as well as Gen 1 DPMS High-Pattern LR-308. We recommend checking with the manufacturer of your lower for compatibility of parts.
