laterallimitsThe Sons of Liberty Gun Works L89 receiver set is a matched upper and lower assembly for AR-style rifles. Both components are designed to form the foundation of a complete firearm build, with precise machining and alignment between the receivers. The set provides compatibility with standard AR-pattern parts and accessories, allowing the user to configure the rifle according to specific preferences for barrel length, handguard type, and other components. The receivers are constructed from aluminum alloy, typical for modern AR platforms, and feature manufacturer markings consistent with Sons of Liberty Gun Works production. Machining on the L89 set includes the integral features required for proper fitment of pins, trigger group, and buffer system. Surfaces are finished to the manufacturer’s specification, providing corrosion resistance and dimensional consistency. This receiver set is in new condition, with no prior assembly or modification indicated. The design supports semi-automatic operation once paired with appropriate internal parts and upper components, following the standard AR architecture. The set includes both the upper and lower receivers only, with no additional parts or accessories specified. It is intended as a base component for a complete rifle build when combined with compatible barrels, bolt carrier groups, and furniture. The matched configuration ensures alignment between the receivers and consistent tolerances throughout assembly. No packaging or supplementary items are described beyond the receiver pair itself.
