I don't feel my Chinese database may be 100% accurate, so please let me know of any errors or additional information. The Chinese AKMs use thicker 1.5mm receivers and they must have really liked the AK-47 because they kept the AK-47 front end and smooth receiver covers on their AKMs. Chinese AKs have also used AK-47 and AKM bayonets and their own permanently attached spike bayonets. Chinese AKs may also with hooded or unhooded FSBs. Some Chinese AKs have threaded barrels, and some don’t. Really, it’s a smorgasbord. As far as I know, all Chinese AKs have only an 800m sight too. Chinese AKs were manufactured at one of several different factories and exported by either Polytech or Norinco, depending on their factory of origin. The Polytech serial numbers reveal the factory that built the gun and the original configuration: PW: Factory 416 Wood stock PF: Factory 416 Underfolder PS: Factory 416 Sidefolder CW: Factory 386 Wood stock CF: Factory 386 Underfolder CS: Factory 386 Sidefolder Polytech also supplied the Legend series which are incredibly nice milled AK-47s, and they were made as either fixed stock, or underfolders. Other Chinese factory stamps include 26, 36 (two styles) and 66. Let’s take a look at some of the Chinese AK. Most of these photos are from Chicom47.net. Polytech Legend fixed stock.
