I think the most interesting part of the original post is the fact that you bought a Zastava M70 in 9.3x62. New or used? If new, who's importing these into the U.S? My understanding is that these are heads-and-shoulders above the Interarms Mark X/Rem. 798/Charles Daly et al in terms of fit and finish.

I'm becoming more tolerant of intolerant people.
