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.
- Matte black hard-coat anodized Mil 8625 Type 3 Class 2
- Machined from 7075-T6 billet aluminum
- Works with standard AR15 components
- Now includes hard engraved Aero Precision “A” Logo
- Includes 3 button head screws for a clean installation. No roll pins needed.
