From the manufacturer
Invented for Marines and refined by combat use, the GripStop acts as an all-in-one hand stop, vertical grip, and barrier stop. The curved serrated side offers a solid support for pulling your AR to your shoulder, while the flat side acts as a handstop and place to brace the gun against a wall, rock, or window frame.
