SKS Dating

It looks like an /816\ arsenal stamp.

Compiled serial data I have seen for this arsenal is sparse, but indicates that it was a very low yearly output factory, with known production dates from the 15th-21st years (1970-1976) of chinese sks production.

As far as when it was imported...I have no idea as I live in the US. But weren't there a few large shipments of chinese sks's to Canada in the past year or so?

[EDIT:] Oops. The op is in Texas. So, this is likely an 80's/90's import. Either that or a Canadian border jumper.
