  • 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

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.
