Cross Armory Flop Stop for AR-15 and M4 Rifles - CRFS-PP

Cross Armory's Flop Stop holds the upper receiver of your AR-15 in the open position for faster, safer, and more convenient reloads where compliance requires separating the upper receiver from the lower receiver. 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. The Flop Stop protects both you and your weapon. This model includes Cross Armory's Pin Pal front takedown pin replacement w
