Cross Armory AR-15 Flop Stop w/Pin Pal Upper Receiver Stabilizer/Front, Black, Small, CRFS-PP

When the receivers are opened the weight of the barrel causes the upper receiver to fall forward pinching fingers and creating an unstable and dangerous weapon. With Cross Armorys FLOP STOP the upper receiver and barrel are held open by the Flop Stop allowing for faster and safer reloads.
