It's the newest addition to Caldwell's line of recoil-reducing rests! A smooth-pivoting elevation system is controlled with a single knob, so adjustments are fast and precise. The heavy-duty steel construction provides a stable and solid shooting platform. Its unique offset frame is designed to accommodate all rifles, including detachable-magazine rifles like the popular M4 platform, as well as lever action guns. The front support is height-adjustable and has a durable rubberized coating that won't scratch or mar your gun.
