Not all is crap. In the Cowboy Action Shooting (CAS) community we use the Winchester 1897 pump shotgun. Well these guns are getting old and hard to come by in certain parts of the country. Well Norinco made a clone that at first was junk. After the third try they are a very good replacement.
I own an original '97 and now use my Norinco at shoots. The original stays in the safe as a back up. In certain areas they seem to get it right and they produce a good product. But they have been known to produce junk at times.
