Okay, I picked up a Yugo M57 with two clips for $179.99 the other day. Aside from being caked with cosmoline which I just got removed (after some Mineral Spirit soaking and scrubbing) I think it is in working order now. However I did hear you could get a 9mm conversion done on this gun with just changing out the barrel and the bushing, but I can not find this anywhere. Any thoughts? (And please don't tell me to buy a new gun, I am aware of that but I like my Russian guns comrades).
