I just got a fairly well-used and slightly abused NHM-91 for a pretty good price, and I'm considering two courses of action for it:
1) Replace the barrel assembly with one from Polytech Parts, or similar, and use it as a beater/shooter
2) Send it off and have a Khyber Pass style build done on it with the abovementioned replacement barrel.
I don't care for the long barrel, and the rear sight housing is heavily rusted, along with the rear sight leaf and top cover, but still operable. It sat in the guys's attic for well over a decade, but it turned out to be in surprisingly good shape after some CLP and elbow grease.
I think this would make one heck of a good project rifle, or maybe even a "battlefield pickup" build.
I turned mine into an RPK style rifle. Threw on a Romanian stock set, replaced the pistol grip, piston and FCG and flash hider for US versions and then put on a AES-10B take-off bipod on it, which worked out well as it is short enought to suit the shorter NHM-91 barrel (which is shorter than a true RPK barrel).
:smile: Check some of the posts from the past and look at the conversion that BigAl did with an NHM. He shortened the barrel and made a "fat" barreled ak out of one and boy does it look sweet. It's in the chinese section so it shouldn't be to hard to find. Big Al, step in here and show 'em what ya got as I know your out there somewhere. If I had a link I'd post it but I'm sure that Big Al will step in here sometime. Mad Max son of Madtechcool
I've got an RPK stock on it now, and a set of handguards from I don't know where, but I'd like some better furniture for it, as well as a replacement rear sight housing and sight assembly.
Those pics have got me warming to the idea of just keeping it as an RPK clone.
Where can I find RPK furniture that will fit this rifle, or that can be made to fit with a little elbow grease and sanding tools?
So, if I pull the barrel to replace the rear sight housing and related parts, will that effect the headspace? I'm thinking that it shouldn't, because the barrel is going right back into place, pins and all, but I've never messed around with this level of maintenance before, so it's Terra Incognita for me.
doubleclaw you can install standard RPK furniture on the rifle. I have Russian laminate on the one above. The only modification needed is the the lower handguard. The retaining plates for real RPKs are much larger than the NHM models. NHM models use standard AK47/AKM retainer plates.
To fit the RPK handguard to the NHM retainer plate was easy, I just used a simple box cutting knife (essentially an exacto blade) to fit the wood.
