I have a Finnish Mosin Nagant M28-76 with the original tapered dovetail scope mount system. It has 26mm rings. I am using an old Kollmorgen Bear Cub scope currently but would like something a bit newer. It has a few small issues and optics are so much better these days. I have been unable to find anything other than old scopes. Or maybe a 1" scope and some shim material would work?
