Fellas, I've been trying to find some mounts for a Swede Mauser that will fit the rear bridge. There are two rear bridge configurations. The early guns have one curvature and the later (M38) guns have another. All of the mounts that I've tried will fit to the point of being level with the front base, but not in full contact with the rear bridge. It is as if the manufactureres found a common point on the two receiver variations and made a rear mount to "generically" fit either if such makes sense. This is primarily a cosmetics issue, but I don't like the idea of a mount with a partial gap underneath. Any ideas?
