Thanks for a great job well done. I have been a fan of the SKS for years, owned 6 different kinds, now own 2 Chinese, but have never seen an explanation of the various types of Chinese rifles.
I just bought an SKS marked NORINCO SKS 7.62x39 KSI K Sport Pomona CA.
The SN is 26539, matching on the receiver, bolt carrier, trigger group and magazine. Stock, top action cover and bolt are also 5 numbers , but not the same numbers. There are no other marks on the rifle except for some very small what appear to be characters in some oriental language, but they don't appear to be Chinese-they are very simple . There is one such stamp on the bolt carrier and a matching stamp on the front sight base.
The stock is heavily grained wood, in very used condition and covered with poorly applied varnish. Front end gas tube wood is completely different wood/ dark brown solid color, unmarked.
Gun is all milled, milled out side on bolt. Trigger is very good and gun seems to function and fit very well. Steel finish is a matt blue.
It looks very similar to a '50's Russian SKS I once had.
Just bought it and cleaned it, have not fired it yet-Bore is excellent, FWIW.
Could this be a Militia rifle or what?
