The Crackshot XBR package includes the Crackshot single shot rifle in .22 cal with a 16.5″ barrel and the XBR 27 Long caliber 20″ barrel that you can swap on your Crackshot rifle. The Crackshot 22 cal is lightweight easy to carry and perfect for small game hunting. With the 20″ barrel the XBR allows you to shoot an arrow from your Crackshot rifle and changes your platform into a whole other gun. The XBR has an inner barrel that allows you to slide the hollow end of a Traditions Firebolt Arrow over this inner barrel until it reaches the end of the barrel. The inner barrel is protected by an outer shroud which also protects the shooter. Keeping the gun pointed down range simply load your arrow break open the action and put in a Traditions XBR Powerload.
