Yeah thanks guys. I am not worried about the receiver cover not matching. Its not like this rifle has historic value anyway. I appreciate it for what it is: A good looking, well functioning SKS.
Norinco is also a commercial production gun right? I have read in many places that CGA is just pre-Norinco. And that both companies are just companies run by the Chinese government to handle exporting of the rifles.
The only commercial production run of SKS specifically made for the American market were the SKS "D" and "M". Also, Some military SKS were modified for Navy Arms in the 1980/90's. There were other stateside companies that also modified military Chinese rifles. Midwest, and a few others - But the Chinese rifles started as military rifles. These could also be considered commercial. But, even the Navy Arms rifles started out as military rifles.
All other sks are made as a military use rifle. China makes these to sell. They used them in their military, their factories produced them for military use. There was no separation in MFG that denoted military or distributor sales. China made them to arm the millions of military they expected to arm. Under their communist work program, they made a lot of them! They later sold them to the highest bidder.
There is no difference in any Chinese SKS made for the military or sold to distributors other than the above mentioned examples. They are all Military rifles.
China sold these rifles with various stamps on the receiver and the ATF requires that import rifles be import marked. There are no stampings that denote military use or commercial production. They are ALL made for sale to world militarises or to distributors who also sell them world wide.
Many Chinese SKS shipped to the US, came directly from the military/Government storage faculties in China and never saw service. They arrived here unfired and unissued. That does not mean they were not military rifles. Many more rifles came from the Chinese military/Government storage faculties that had seen service, battle weary, bruised and used.
So - If it is marked, Norinco, Polytec etc.....That is simply an import mark denoting the importer, not a designation of the rifle.
There is no question of military use when there are bring back papers as a documented war trophy.
To designate any Chinese SKS that is not a sks "D" or "M", or stateside Bubba job- -- "Commercial" -- is incorrect.
