Aero Precision Gen 2 AR-15 Stripped Lower Receiver Black

The Aero Precision AR-15 Gen 2 Stripped Lower Receiver is the perfect base for your custom AR15 build. Machined to mil-spec dimensions, Aero Precision lowers work with standard AR15 components and ensure the highest quality with a correct component interface. The upper tensioning feature allows users to fine tune the fit of the upper and lower receiver through the use of a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver. An increased magwell flare allows for easier insertion of magazines and provides a sleeker look.
