This Rear Bag is the perfect rear support for a gunstock or a pistol shooting support. This smaller bag is more compact and is easy to transport. It has a pyramid shape to prevent tipping over under recoil. It's a much smarter design vs. the rectangular shapes out there that tip over. Non-skid base prevents moving around on the bench. 1000-denier material = tough, unlike the cheap material from the lesser quality bags on the market.
