(posted this in troubleshooting, but no answers..)
I have a NHM-91 by Norinco. Have had issues with it for a long time & I'm finally getting around to fixing it.
It will fire first shot after charging with the bolt carrier no problem, next shot, just barely dimples the primer.
I first cleaned very thoroughly, changed the firing pin.. Just put a new hammer & hammer/trigger spring in it, but discovered the problem.
Broken disconnector & no disconnector spring!
So, I ordered the disconnector & spring & installed them. Looks good.. only problem is the disconnector still won't hold onto the hammer. If I have pressure on it, by holding all the way back on the trigger, I can hold the hammer w/ the disconnector, but as soon as I release the pressure, disconnector releases & the trigger hooks hold onto it.
I looked at the original hammer & found the disconnector notch is slightly larger on the original hammer, so put it back in. Still doesn't hold onto the hammer.. I also compared what was left of the original disconnector & it looks identical to the new one.
I'm out of ideas.. I still need to take it out & see how she runs, but don't have much hope, since the disconnector never holds the hammer. I don't see how it could get out of alignment so bad, the hammer & trigger pins would have to move..
Please Help!!
