Aero Precision AR15 Stripped Lower Receiver, Gen 2 - BLK - BLEM

Aero Precision AR15 Stripped Lower Receiver, Gen 2 - BLK - BLEM

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

This product is blemished. Blemishes may include:

  • Plating inconsistencies
  • Pits
  • Scratches

  • Flaws in finish

Aero blemished products are fully functional, they just didn't meet their high standards. They are a great product at a discounted price for someone who doesn't mind a slight imperfection.
