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.
