The NHM-91 is a semi-automatic civilian development of the Russian Kalashnikov AKM and RPK infantry small arm built by Norinco of China and marketed in the U.S. by China Sports Inc. of Ontario, California (CSI Ont, CA).
A civilian semi-auto variant of the Chinese Type 56 assault rifle. Based on the Russian RPK light machine gun, the NHM features a stronger receiver and a longer, thicker-profile chrome-lined barrel measuring 20 inchescompared 23.2 of the original RPK, along with a forward-mounted steel bipod.
Like the RPK, the NHM-91 utilizes a heavier-gauge stamped sheet metal receiver built from 1.5mm-thick stamped sheet metal instead of the 1mm thickness typical of a Soviet or European AKM. This results in increased rigidity, heavier weight, and improved overall accuracy.
