Aero Precision's AR-15 Gen 2 Stripped Lower Receiver is the perfect base for your custom AR-15 build. Machined to mil-spec dimensions, Aero's lowers work with standard AR-15 components and ensure the highest quality with a correct component interface.
Gen 2 Improvements:
• Upper Tension Screw - 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 AR-15 upper receiver.
• Increased Magwell Flare - Allows for easier insertion of magazines and provides a sleeker look.
