As for the bolt carrier, it is original Tula. The gas piston is shaved off as part of deactivation. Also, an AKSU bolt barrier is much different then a standard AK. Biggest piece is that the charging handle is smaller.
Rumor mill on these 1993 semi autos was that they were semi autos meant for the West, but that it never happened. They were made up from the remaining parts at Tula. They have since dried up in Russia and Europe. Another run of deacts was done in 2008 but those were full aut receivers, and were simply restamped 1993s.
They are not importable, as they are not a Saiga or Vepr. They are also a semi auto "assault rifle" receiver, which is forbidden.
