All the parts you need to get started on your next Mk3 build. Combine this kit with a buttstock kit to complete your lower group. Compatible with CMMG Mk3 Lowers and most LR308 type lowers.
**Not all 308 lowers are the same. Our kit is designed to work with our lowers, and are “Mil-Spec”. We would recommend checking with the manufacturer of your lower for compatibility of parts if you are not using our receiver**
**All parts meet or exceed mil-spec**
