A few years ago I purchased an M41b through a vendor that got all the remaining examples from Samco. The scope mount and base numbers are not matching. The scope mount does not slide completely to the recoil stop, and I'm not going to force it. I used Kroil and a rubber mallet to gently tap the scope and mount off the base, and found no corrosion or grit. The mount slides on properly, then gets really tight in the last 1/4". The handle that cams the mount into place won't budge the mount, and I'm not going to force it. I was hoping someone can instruct me on how to proceed with getting the mount properly secured on the base.
I assume a serial matched mount and base were mated during machining and installation, so I may have to lap the parts to get them to properly fit? Is/are there fasteners I need to tighten or adjust?
I've only tinkered with it as far as I stated in the first paragraph. I'd like to begin enjoying it at the range, but I need to fix this issue first.
