Rugged, semi-auto receiver made from a high-quality forging is built to handle the hard use and abuse of tactical and competitive shooting. Forged from 7075 T6 aluminum alloy, for an extra margin of strength and rigidity over standard 6061 alloy receivers, before precision machining to final mil-spec dimensions. Hardcoat anodized for added strength, then Teflon® coated for outstanding resistance to scuffs, scratches, surface abrasion, and discoloration from gun oils. Stripped lower receiver ready for a full custom build, CMMG’s engineers designed custom fixtures for final grinding of 10 separate contact surfaces on the trigger, disconnector, and hammer to ensure a crisp, precise release.
