Even though it's a Norinco import, this version is known as a Chinese Public Security SKS. As I understand it the Chinese Security Forces are like their Gestapo or Stassi, if they come get you they keep you, it's not good. A Chinese Security SKS is a Type 56 Carbine produced at one of three specific state-owned/controlled arsenals expressly for issue to soldiers of the National Public Security Forces and are marked as such. It has two two Chinese ideographs on the right side of the receiver. Also, the bolt carrier is a very dull matte finish. They are identified by arsenal /26\, /016\, and [0141], all though a few others have been noted, those are the most common. They only were imported through KFS (Keng’s Firearms Specialties) located in Georgia. From what I have read, it was a very small (a pallet or two was the answer I got) lot that came through that importer.
My example, I believe the stock possibly got changed at some point, as most I see have a numbered stock with the rear side sling mount. But being a Chinese, who knows? This stock is an unnumbered Chinese with bottom sling hanger. The metal however is all number matching. This example is a later pin barrel model, and one thing I do notice, the finish work, trigger ect. is better than my other Chinese rifles. The other thing, maybe it's just me, it does seem slightly more accurate than many of my other SKS's on equal shooting terms.
I thought I would share, even though it is a Chinese, it is one of the more uncommon Chinese models out floating around. Figured it may help some of those who may stumble on to one and question the markings.
