matching serial number marked "дг 108” I believe it’s a 1947 Russian star stamp I can take the scope off to check. When I got the rifle it had the KNS adapter block on it so I put the cheap 2-7 long eye relief scope shoots nice fun little gun didn’t want to put tactical rail on it and ruin the style. Would’ve super easy to take off the scope mount it’s held in by bolts not welded if you wanna factory stock iron leaf sight it should work.
