I can't think of any specific firearm type that Norinco makes which isn't based on a design who'se patents would have expired decades ago. Funny how the people who are the most vocal about "knock-offs" also own non-armalite/colt AR's ... Heck even some of your "high quality" or "premium" European or North-American firearms are a bunch of Chinese-made parts, finished and partially assembled in either the Philippines or Indonesia (among other 3rd world hell holes), and then shipped to whichever "manufacturer" ordered them in order to get fitted and finished, then stamped with your premium brand ...
