Improved AR-15 Lower For Easy Installation and Reliable Performance

Gen 2 Improvements

  • Upper Tension Screw – This 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.
