Caldwell’s Tack Driver X Mini Bag shooting rest is one of the most versatile shooting bags on the market today. This is a great bag for getting a stable shooting position, regardless of the situation. With a unique design that allows for a wide variety of rest choices, the Tack Driver X is ideal for PRS match use on barricades, roof tops, window and port openings or any other surface. The versatile design also works well for sighting in on a bench and hunting in the field. An adjustable strap allows for height adjustment and acts as a carry handle. A rubberized bottom material prevents sliding for a stable shooting position.
