I picked up a real nice NHM-91 at the gun show this weekend. The guy was selling it for a friend of his and wasn't sure what it was. He said it was like a MAC 90 only with a longer barrel. I asked him if I could look at it, picked it up and looked at the reciever and saw it was a Norinco NHM-91. It is a post ban gun and it is in very good condition. It came with a 40 round magazine. I took it out and shot it at the benchrest range today and it grouped real tight. I did not have to adjust the sights as the previous owner had already done a pretty good job. It has the stamped reciever. He wanted $500 and would have taken $425 he said if his friend had not said $450 or bring it back home. I was willing to go $450 for it as this was the exact model I had decided I was going to purchase in a AK. And true to the words I have read on this board about NHM's it had a real nice trigger pull. I am going to have to get a manual now so I will know how to field strip it for cleaning. I saw a 2 hour special on the history channel a few weeks ago about Mikhail Kalishnikov and the story behind the AK's. It pretty well sold me that this is a great design and he was something of a firearms genius. This gun makes a great companion to my M1 Carbine. Next will be a good AR-15.
