I have owned a number of SKS,s over the years . The Norinco guns were built by the P.L.A. at the same factories that built military firearms . The MOD.D was a SKS built to take AK mag,s . It was made for the American market as it was not a military item . I may be wrong ,but have never seen it listed that way . The SKS rifles from China are well made and are a good buy . The YUGO SKS is a well made firearm as well . The U.S.A. mag,s that replace the regular 10 rd. mag. can be reliable but I find they must be fitted to that rifle. I have only shot the Russian and Romanian SKS rifles but they seemed well made and shot fine. If I had a choice it would be a Norinco PARA model or the SKS/D model. I have also found that using stripper clips , the system works better than using the U.S.A. magazines . Also it seems the SKS is going up in price . I would also get stripper clips and ammo. Hope this helps , good luck and enjoy the SKS. ITs a great rifle!
