The Cross Armory Flop Stop with Pin Pal (brand part number CRFSPP) holds an AR-15’s upper receiver in the open position for faster, safer reloads in situations where compliance requires separating the upper from the lower receiver. Without it, the weight of the barrel causes the open upper receiver to fall forward, pinching fingers and creating an unstable, dangerous weapon during a reload. This model includes Cross Armory’s Pin Pal front takedown pin replacement, which adds a locking nut and a lubricated captive bearing to reduce wear at the front pivot point. The Pin Pal is made from 4140 ordnance steel with a melonite hard coat and is removable if you want to return to a factory configuration.
