hey im new here and i just wanted to know what the value of NHM 90s are and how well they are made compared to other norincos. mine is stamped and has a threaded barrel. i was also thinking about putting a Bsquare mount on it so i can put a red dot on it in the future. thanks for any input. i paid 600 for it and the guy said he only shot a couple hundred rounds but the gas pistin looks like it has some wear on it.
