There are no brand new SKS. Someone might say NIB, but that doesn't mean it was made last week. The SKS hasn't been built for years, and importation from China was ended during the Clinton years. The recent batch of imports of Chinese SKS came from Albania, and were originally produced in the late 1950's typically.
The SKS is a quality built piece, regardless of country of origin IMO. Look for the best condition you can, and keep it in an original configuration. All the "tac-T-cool" modifications do not help the SKS.
