The China North Industries Corporation, officially abbreviated as Norinco, is a Chinese company that manufactures vehicles (trucks, cars and motorcycles), machinery, optical-electronic products, oil field equipment, chemicals, light industrial products, explosives and blast materials, civil and military firearms and ammunition.
Norinco is also involved in domestic civil construction projects.
For example, a serial number 2958E44--1967 indicates that the SKS was manufactured in 1967. Add the first digit in a Chinese serial number to 1956 to determine the manufacturing date.
Advantages over the SKS were the selective-fire option, a rifle that was lighter, had more magazine capacity, not to mention that it was less labor-intensive to manufacture.The SKS was to designed and produced as a service firearm that would have a limited lifespan between 2 rifles but utilized a reliable operating mechanism design.This rifle was a less radical "just in case" for the AK-47's experimental design.The SKS‑M was equipped with either a thumbhole style stock or a fancy Monte Carlo style stock. It has the handle mounted on the spike and slides up and down to attach. I have modified standard bayo's to fit the rivit as a last resort.These will usually have either SKS Sporter, SKS M, SKS NR, or MC 5D stamped on the side of the receiver. Edit: Thanks for bayo info, would have never known on this. Mike No point in posting a photo of mine since it looks exactly like your SKS M. Mine didn't come with an original magazine, but it resembles the SKS-D.Norinco is also known outside of China for its high-tech defense products.Norinco produces precision strike systems, amphibious assault weapons and equipment, long-range suppression weapon systems, anti-aircraft & anti-missile systems, information & night vision products, high-effect destruction systems, Established in 1980 with the approval of the State Council of China, China North Industries Corporation (NORINCO) is an enterprise group engaged in both products and capital operation, integrated with R&D, manufacturing, marketing, and services.The SKS remains popular and is also used by several African, Asian, and Middle Eastern armies, as well as guerrillas in Bosnia, Somalia and throughout Africa and Southeast Asia.One major reason that the design became so prolific is that during the Cold War the Soviet Union shared design and production details with its allies.I have the stripper clip guide, bayo lug, spike bayonet, normal stock, etc., but still not sure, I'll get home and get the pic on tonight.Here are three shots of the very first conversion by Midwest Ordnance (needs a new catagory) this is the one that the Chinese came over and looked at then went back and made the 84's and then the D's.
