ADM4 Stripped Lower Receiver-SB Brace

The ADM4 billet 7075-T6 lower receiver features a Type III Teflon impregnated hardcoat anodized finish, is outfitted with our proprietary Ambidextrous magazine release, Ambidextrous bolt catch and release lever, and our dimpled take down and pivot pins. The magazine well features a slick side design, similar to a milspec lower for a more traditional AR15 look. 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. The ADM4 Lower receiver kit will ship with all proprietary ambidextrous controls installed and include our dimpled take down/pivot pins. **Due to the design of the Ambi Bolt Catch/Release, the lower is NOT Compatible with certain triggers that utilize anti-rotation pins that use external screws or plates. We have developed a low head pin to be used with CMC Triggers. Standard GI type triggers, Drop in triggers that use standard pins, and Geissele triggers WILL work with with this lower.**
