HELLLLLLLP!!!!! I have a Steyr Standard 300M CISM in 7.5x55mm Swiss. It's an awesome rifle and extremely accurate. It's so accurate I want to find scope rings that will fit the dovetail base that is mounted on it. It currently has Steyr diopter match sights. Does anybody know what kind of rings will fit this dovetail. The diopter slides on the top smaller dovetail on top. Two thumb screws loosen and it comes right off. I want to find rings that will allow me to readily put the scope on. What kind of rings do I need?
