American Defense Mfg

The ADM UIC billet 7075-T6 lower receiver features a Type III Teflon impregnated hardcoat anodized finish, is outfitted with American's proprietary Ambidextrous magazine release, Ambidextrous bolt catch and release, and dimpled Take down and Pivot pins. The magazine well features reinforcing ribs that make the magazine well 40% stronger than mil-spec forged at only half ounce of weight change. The trigger guard is ready for winter gloves without manipulation. Radii and chamfers throughout make this billet lower a marvel that stretches the capabilities of modern production CNC manufacturing. A 20 degree competition style mag well is concealed in the design, allowing lightning fast magazine changes. An integral upper/lower tension adjustment screw allows the end user to compensate for tolerance between your upper receivers and your favorite lower.
