Have a particular grip or trigger you want to use in your next AR10/LR-308 build? The CMMG® ZEROED™ AR10 (Mk3/.308WIN) Gunbuilder’s Kit includes the essential parts except the most commonly upgraded ones like: Trigger Guard, Fire Control Group, and Pistol Grip. Check out our interactive install walkthrough video below or read the CMMG Resources LPK Install article for an in-depth breakdown. Not all .308 lowers are the same. Our kit is designed to work with our lowers (Gen 1 DPMS High-Pattern LR-308) and meet or exceed mil-spec.
