ZEROED Lower Parts Kit, Mk3

Ready to complete your AR10/LR-308 lower receiver? The CMMG® ZEROED™ AR10 (Mk3/.308WIN) lower parts kit is just the thing you need. All parts are made in the USA and comes in convenient color-coded packets to make assembly and part identification a breeze. Check out our interactive install walkthrough video below or read the CMMG Resources LPK Install article for an in-depth breakdown. Don’t forget a Buttstock or Brace kit to complete your pistol or rifle lower. 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. We would recommend checking with the manufacturer of your lower for compatibility of parts if you are not using our receiver.
