Wilson Combat Lower Receiver Kit – AR-10 / .308 Platforms

The Wilson Combat Lower Receiver Kit provides a complete assembly of small parts and hardware for completing an AR-10 / .308 lower receiver build. This kit includes the internal components needed to build a functional lower—trigger and hammer pins, bolt catch, magazine catch assembly, takedown pins, selector detent and spring, and other critical small parts that turn a stripped lower into a working receiver. It's designed for builders assembling a custom AR-10 or replacing worn or damaged components.

All parts are manufactured to Wilson Combat's specifications for proper fit and long-term reliability. Installation requires basic gunsmithing tools and familiarity with AR-pattern assembly procedures. This kit does not include the fire control group (trigger, hammer, disconnector) or pistol grip—those must be sourced separately.
