All the parts you need to get started on you 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.
