Cross Armory AR-15 FLOP STOP and PIN PAL are designed to be used with the Cross Armory SAFE MAG to minimize the pivot of your upper on your lower to allow for faster, more conventional reloads in California. Made of steel, the PIN PAL simply replaces your takedown pin and the FLOP STOP keeps the upper from completely opening.
