I know a guy that has had a nhm-91 for sale since last spring. The rifle is stock with a 75rnd Chinese drum priced between $600 to $700, I do not remember that exact price. I am sure that I could get him to throw in a couple of standard AK magazines for his asking price. Chinese drums are going for $100 if you are lucky. Standard AK magazines for $15 or so. Subtract about $175 from the asking price for the magazines. That leaves around $425 for a Chinese AK with thicker receiver, built on military AK machinery, with longer chrome lined barrel with by-pod (I have heard the by-pod sucks) for a price lower that you can get a new Romaian or Hungarian AK variant. If you have other SKS I would run and make the trade. Is the Drum Chinese or of other manufacture? It may affect the price by $25 to $50 but still is a good price. Also see if you can shoot it first.
