Yeah it is a factory 216.

/216\ "Chinese Characters" R17*****

The importer stamp says "SKS 7.62x39 CHINA NORINCO CSI ONT CA"

All matching #'s

The inside of the stock looks fairly old....

Does the sling mount on the side of the stock mean anything cause i've seen them on the bottom of some Chinese sks

The stock is cut for spike bayo....
