I realize you didn't say SKS's can't come in, and you're right that currently there's no recent imports available for sale and definitely no steady stream of imports, but SKS's occasionally are imported in small numbers.
You probably recall 3 years ago Classic received a few hundred beautyful Yugo ceremonial SKS's from Serbia and recently some used Chinese rifles imported from some other country than China
Consensus seems to be they were stored in Albania for over 20 years, thus allowing their import. Many have so called "trench art" that matches that region.
