The American Defense Manufacturing UIC (brand part no. AD-UICLS-BLK) is a billet 7075-T6 stripped AR-15 lower receiver chambered in .223 Remington/5.56 NATO, outfitted with American Defense’s proprietary ambidextrous magazine release and ambidextrous bolt catch/release lever along with dimpled takedown and pivot pins. An installed mil-spec magazine release assembly and a Type III Teflon-impregnated hardcoat anodized finish round out the package. It ships stripped, so builders can select their own trigger and buffer system while keeping ADM’s ambidextrous control layout built into the receiver itself. It’s a strong option for shooters who want true ambi function without installing aftermarket ambi parts on a standard lower.
