Our Mk3 Gun builders kit includes most of the necessary parts to build up your lower group except the commonly upgraded parts. Does not include Fire Control Group, and pistol grip. 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.
