CVObiker,
I'm sure you are correct........I was referencing some Chinese versions that my friend has; he has several, and we've put a lot of rounds thru them. Some of them have machined parts, some have stamped parts. He bought a crate of them back in the 80's when he had a FFL. Some of them came in very heavy carboard boxes that "looked" military, and they had red stars on the boxes. That's what I was referring to.
I prefer the Russian SKS's, at least the ones I've shot. As you stated they seem to have better quality than the Chinese versions. Some of the Chinese versions have been pieced together from "non-matching" parts; several key pieces with different numbers on them. The Russian versions I've seen are almost always "numbers matching" on mag well, trigger guard, upper receiver, lower receiver, stock, etc.
I don't have any exposure to the Albanian and Yugo.
