Caldwell rear bag - Caldwell Deluxe Universal Rear Shooting Bags

Great product. It came filled and it continues to hold its shape nicely. Supports butt-stock well and allows your rifle to recoil naturally. This product is a must when you're sighting in a rifle after mounting a new scope. This product is so much more convenient than those that require filling because those bags are both difficult to fill and are prone to leaking. The Caldwell rear bag has a velcro backed cover to the fill area.
