Larue Tactical LT15X01BLK Stripped Lower Receiver

The Larue Tactical LT15X01BLK Stripped Lower Receiver is a precision-machined AR-15 lower receiver designed as the regulated firearm component for custom rifle builds. Stripped lowers serve as the foundation for modular rifle construction, allowing builders to customize every remaining component to meet specific mission requirements, platform standards, or compliance constraints. This stripped lower provides the serialized, registered base from which a complete AR-pattern rifle assembly begins.

Larue Tactical manufactures this receiver to precision tolerances that ensure reliable function across diverse upper receiver assemblies and trigger group configurations. The LT15X01BLK designation indicates a black-finished AR-15 lower receiver platform compatible with standard AR-15 parts kits, fire control groups, and buffer tube assemblies. At 0.9 lbs, the receiver delivers a solid foundation without excess weight, and the compact dimensions (4.5 x 2.4 x 8.8 inches) facilitate handling and storage during assembly or installation. The stripped configuration means the lower arrives without fire control components, giving builders full control over trigger quality, safety lever type, and overall system tuning for their specific application.

Stripped AR-15 lower receivers appeal to firearms enthusiasts, gunsmiths, law enforcement armorers, and military personnel who assemble purpose-built rifle systems for duty, training, sport, or authorized collection. Builders select stripped lowers when they require a specific brand's reputation for precision manufacturing, compliance with local firearm regulations, or integration into standardized platform ecosystems. This receiver accommodates the full spectrum of AR-15 upper assemblies, barrel profiles, stock configurations, and trigger systems available on the market, making it adaptable to roles ranging from precision rifle work to dynamic training scenarios.

The AR-15 platform's modular design has made the stripped lower the standard building block for custom rifle development since the platform's commercial introduction. Larue Tactical's precision manufacturing positions this receiver within the professional-grade segment of the market, where tight tolerances and consistent quality support duty-grade performance expectations. Builders who prioritize component consistency and manufacturing rigor source stripped lowers from established precision manufacturers rather than commodity suppliers, particularly when the completed rifle will see sustained use.
