This is the board to ask and find info on the older mil-surplus firearms.

Scroll down to the Mauser board and ask your questions.
I bought a Yugo M-48 from Big-5 Sporting goods for $139.00, all matching numbers, like new. Cleaned it up, bought some surplus 8mm from Eric the Ammoman, shot it no problems. At 100 yards offhand it groups (mine does) at 2 inches, no sight adjustments made. There is no real kick (of course I don't think that a 12 gauge shooting 3 inch magnum slugs has much of a kick either) to speak of, just make sure that you clean it up with a 50/50 mixture of amonia and water after shooting, that older mil-surplus ammo is quite corossive.
