Am Def Uic Strppd Lower Receiver Blk

The American Defense Manufacturing UIC Stripped Lower Receiver in Black is a precision-machined billet component engineered for AR-platform builders who demand exacting tolerances and proven reliability. As a stripped lower receiver, this component serves as the serialized foundation of your custom rifle build and is compatible with 223 Remington and 5.56 NATO ammunition configurations. The anodized black finish provides corrosion resistance suitable for variable operational environments, while the pre-installed ambidextrous magazine release and bolt catch eliminate critical assembly steps without compromising functionality.

Billet construction delivers tighter dimensional control than forged alternatives, translating to consistent trigger geometry and reliable magazine seating across varied ammunition and magazine platforms. The ambidextrous controls accommodate both right-handed and left-handed shooters, addressing operational flexibility in training and field scenarios where shooter transition or mixed-crew operations occur. At 0.94 lbs and measuring 8.75 inches in length, the lower receiver integrates smoothly into standard AR-15 upper receiver assemblies and furniture configurations. The black anodized finish resists wear and environmental degradation better than bare aluminum, extending service life in corrosive or high-humidity conditions.

This component is purpose-built for precision rifle builders, law enforcement armorer stockists, and military support operations requiring serialized lower receiver platforms. Stripped lowers allow complete customization of trigger systems, stock configurations, and ergonomic accessories without factory constraints. Operators evaluating American Defense for budget-tier or upgrade builds benefit from the manufacturer's known reputation for dimensional accuracy and simplified assembly—no fitment problems at the critical interface between lower and upper receiver halves.

The AD-UICLS-BLK represents a straightforward, unfussy approach to lower receiver selection: verified dimensions, pre-installed critical components, and an anodized finish that survives field use. No frills, no proprietary ergonomics—just a solid foundation for professional or competitive AR builds.
