The JP GMR-15 Stripped Lower Receiver has many cool features, both aesthetic and useful. This receiver is machined from a solid billet of aluminium to exacting tolerances. Mil-Spec hard coat anodizing protects this lower from anything that you may plan to put it through. The magazine well is milled out to make inserting of magazines as fast as possible and to help lighten up the receiver. The trigger guard is machined out with the rest of the receiver, making for a stronger receiver. After the last round is fired, the bolt will lock back to the rear indicating an empty mag. The magazine release has been moved slightly to make finger placement and reloads more natural. The EZ trigger has been installed by JP, so you know it will be perfect out of the box with a crisp, light break.
