I've had examples from China, Egypt, Romania, Bulgaria, and Yugoslavia over the years. All functioned perfectly but fit and finish varied from pretty nice to WTF were they thinking.

Honestly, if I were looking for one today, I would be keeping an eye out for a Norinco or Poly Tech. The ones I had were nicely blued and the fit of all the parts was spot on. I knew a guy that had to send one of his Norincos back because it had an extra hole and pin in the receiver that shouldn't have been there. How's that for "mil spec"?
