Cross Armory Flop Stop with Pin Pal — AR-15, Black Melonite

The Cross Armory Flop Stop holds the upper receiver of an AR-15 in the open position to enable faster, safer, and more convenient reloads when regulations require separating the upper and lower receivers. It prevents the upper receiver from falling forward under the weight of the barrel, which can pinch fingers or destabilize the rifle. This model includes Cross Armory’s Pin Pal front takedown pin replacement with a locking nut and a lubricated captive bearing to help reduce wear on the front pivot point. The Pin Pal is made from 4140 ordnance steel with a melonite hard coat and is removable to return to factory configuration.
