I have an M38 Mauser my father gave me that shoots rather well, but my father did the gunsmithing to the rear of th reciever to attach th scope base. When i wnet to mount a ne scope on it, if found that when you tightened the rear ring down that there was a 1/8" gap between the front ring and the underside of the scope. Can anyone give me an idea on what procedure I should use to rectify this problem? i have heard people mention using shims to solve the problem, but i have also heard people using sandpaper to change the angle of the inside of the rings.
