Description

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.

Features:

  • 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.

Our state-of-the-art Enhanced Upper Receiver combines the handguard mounting platform with the upper itself, condensing the parts needed to mount a free-floated handguard to a mere 8 screws.
