ADM UIC Ambidextrous Stripped Lower Receiver

American Defense Manufacturing's UIC (Universal Improved Carbine) lower receiver represents the evolution of billet design with duty-grade durability. Machined from 7075-T6 billet aluminum with Type III Teflon-impregnated hardcoat anodizing, the UIC delivers premium features without sacrificing strength. The standout innovation is the reinforced magwell with integrated ribs that make it 40% stronger than mil-spec forged lowers while adding only half an ounce.

The fully ambidextrous controls include proprietary magazine release and bolt catch/release systems that provide intuitive operation for both left and right-handed shooters. The 20-degree competition magwell is integrated into the receiver's profile, allowing lightning-fast magazine changes without the bulk of external magwell flares. The trigger guard is designed for gloved operation without manipulation.

An integral upper/lower tension screw allows precise adjustment to eliminate receiver wobble with any upper. The dimpled takedown and pivot pins provide enhanced tactile feedback during disassembly. At 11 ounces, the UIC is lighter than many billet alternatives while maintaining superior strength. Note that this lower is not compatible with triggers using anti-rotation pins with external screws or plates, but works with standard GI triggers, drop-in triggers using standard pins, and all Geissele triggers.
