This is a rare variant of SKS that Norinco only made a few models of, the entire stock is made of a bakelite/fiberglass composite instead of wood, this furniture is very uncommon.  Additionally, all of the serialized parts seem to have matching numbers, besides the topcover which was swapped out for a Picatinny adaptor. 
 
This variant of the SKS also includes the Russian style bayonet, as opposed to the lower quality "screwdriver" style bayonet on most Norinco SKS's.  Most notably, this variant features a 20rd fixed magazine with the Soviet star stamped into it.  Altogether, this setup has "cool factor" written all over it.
 
Until the rifle roster is released, this rifle can still be transferred in MA, however the fixed magazine can NOT be transferred with this gun.  We can provide a discount to MA residents.  If you have any questions about this SKS, dont hesitate to reach out to us.
