CMMG

CMMG's Lower Parts Kits contain all of the necessary parts to complete an AR15 lower receiver, except for the buffer tube and butt stock. Built on the mil-spec standard, the lower parts kit includes a single stage trigger with polished sear surfaces for a clean, crisp trigger break. It features an ambidextrous selector and is broken down into a color-coded bag that makes it easy to locate individual parts without frustration.
