Figured I'd show off a couple M91/30 Mosin Nagants I just picked up recently. One of them is a hex receiver and the other is a Finn capture. The Finn Capture has some pitting and rust on the barrel near the front sight. Any idea on whether I should try to fix/restore it? I've built AKs from parts kits before but this is a bit different. Part of me wants to just leave it as is due to the history, but I'd rather the pitting and rusting not spread and get worse.
