This has been gathering dust for 5 years.
First post of "I'll take it" gets it.

Will this work with the barrel length of a nhm-91?

I dont know.
I think it should work with any standard AK, but I'm not sure about the older Chinese ones. I think just the YUugos are different, but Im not an expert.
I'll try googling it.

Found this:

Finish: Black, MIL-SPEC hardcoat anodizing
FEATURES
This Railed Gas Tube will fit Russian, Romanian, Bulgarian, some Chinese, US and Others AKs (stamped and milled) with a standard length gas tube. Handguards will fit stamped receiver AKs (not milled receiver) and will work with some Bulgarian, Romanian and Egyptian lower handguard retainers. Others may need some minor modification to fit properly. Cooling holes along the side allow the rail to run cool after extended firing.

Features:

• Lightweight and sleek

• Easy installation of mounts and accessories

• Replaces factory handguards easily

• No gunsmithing required

Note: May not fit all AK variants
