The Caldwell DeadShot Air Front and Rear Shooting Rest Combo uses Caldwell Air Rest Technology and a molded, all-weather design that stands up to the elements. The rear bag nests inside the front bag for storage, and multiple height options give over 50 configurations to fit bolt-action rifles, shotguns, lever guns, AR-style rifles and handguns. The durable molded bags won't tear like nylon or be damaged by muzzle blast.
