The Nano-ProTM stock recovers even faster after the shot than the Nano-XR and offer a flatter trajectory and higher accuracy at long distances. This stock has the smallest diameter of any other stock, virtually eliminating lateral shift due to wind. Unlike conventional aluminium-carbon shafts, the Nano-Pro does not flex permanently and retains its initial spine
