Go to the "Weaver" website ands they have all the info. you need for any model gun and the mounts and rings to fit it. They make and sell scope rings and mounts. All you need to know is the size scope you have and the type of gun you have. You can even call them and order direct and save some money. They helped me with a similar problem last year and were a great help, very poilite & fast service. Good luck.
