NEW AERO PRECISION X15 LOWER RECEIVER.

Our AR15 Gen 2 Stripped Lower Receiver is the perfect base for your custom AR15 build. Machined to mil-spec dimensions, our lowers work with standard AR15 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 AR15 upper receiver.
• Increased Magwell Flare – Allows for easier insertion of magazines and provides a sleeker look.

Includes:

• Stripped AR15 Lower Receiver, Gen 2
• Nylon tipped tensioning set screw
