Hey guys, i have a Mosin Nagant, and im thinking of scoping it. I dont want a scout setup, but a WWII scope/mount, repro of course. My rifle is a 1938 Izhevsk with a round receiver. Im not sure what kind of scope it would have been paired with. A PU would be easier to mount, as im no gunsmith and would be a little nervous about mounting a PE over the chamber, but will mount whatever setup is historically accurate. HELP!
