I also have a rifle that looks like the one pictured. When I bought it the barrel had been cut about 4 inches from the back end and sleeved with another barrel about 38 cal. As I had no use for such a caliber I installed a new barrel chambered for .22 K-Hornet. Made a rib for scope mounts and had to make a forend. Haven't shot it yet but looks like FUN...... Bill
