The linchpin of our MCS system, this lower receiver is made from 7075 T6 aircraft aluminum forging. It comes with a .223 magazine well, which is interchangeable with other magazine wells in our multi-caliber system. With a Mil Standard Type III hard coat anodize finish, our lower receivers are made to give you years of trouble-free service. This lower receiver assembly is fully assembled with all internal components and a six-position adjustable stock. The fire control group is a single stage mil-spec system and the buttstock uses a commercial buffer tube.
