If this is actually a Paratrooper, it will have a markedly shorter than standard barrel. The "M" version will also accept AK mags. The current crop of Chinese SKS rifles has been languishing in Customs for a while, awaiting a ruling on whether they were restricted under the Executive Order banning import of Chinese firearms. Apparently, they were from a different source.
They are 90% beaters. That said, locally, they have been selling for $400-450. Joking, I offered one dealer my Chinese SKS, pre-ban, with bayonet, and he was willing to give me $450 for it. Said that a gun in such good condition could get him $650.00, or up. He also offered me $1000.00 for my unissued Albanian SKS!!
