So a commercial 330 scope that seemed to had been militarized. Still the first time for me I see a scope matched to a rifle action. This was nothing done factory, so it should minimum had been through an Arsenal overhaul, but if it were through an arsenal, it would carry an arsenal stamp on the stock, what so far you had not given information upon, but I suspect not. Chuck had already pointed out the crossbolts, I had pointed out the K marked cutoff that identifies the stock as a replacement stock.
After full consideration I think your rifle carries a replacement stock that had been stamped to look like it comes from factory. Check https://bardalls.com/ . Here you can buy all stamps that you can find on your rifle.
