Yahooo... 
How to Remove Your Xhinese Flash Suppressor
Oh yeah, big shout out to KCCO for letting us BEAT on his FS unit!
The Norinco dudes are not responding to my emails about the Assault Weapon Ban from 1992-4. Bill Clinton passed that law and the Qhinese started welding the flash suppressor to entend the barrel and unitize the two together. I've been trying to save them a few manufacturing (saves money) steps for the past 15 years by trying to tell them that AWB of 92-4 has sunset'ed and Bill Clinton (Dem) in no longer the POTUS (Prez of US).
Nevertheless, here we are with flash suppressors welded on. We need to access them so that I can 180 Flip Trick the gas cylinder lock and quite possibly avoid using a shim or two to tighten the FZCK out of that gas cylinder assembly....
Okay, remove the front sight and put it aside... Then clamp the receiver, usually by the receiver mortise(s), those two tangs that hang beneath the bolt and lock the trigger group. Go and have a look if you are not sure.
Now using (sometimes a 1/16" Allen key, all depends on what set screw the high school shop class kids used) an Allen key, remove that set screw and don't lose it...
Take a set of Castle Nut pliers and loosen that castle nut. Hint: I like to take a plastic mallet and / or wooden block or hockey puck and give that front of flash suppressor whack to the rear so that some tension (real or perceived) can be taken away from the castle nut. Now get that castle nut loosened.
Then keep that first aid kit handy, you might draw blood if the welding job was done on a Wednesday in front of the High School Shop Teacher and Ministry of Edumacation Inspector...
Another view of where to locate the cold chisel , beneath the dovetail of the front sight. Now have a look at the castle nut... we have rotated it FORWARD and created a GAP for the welded FS unit to move once the welds are "broken". If your rifle was welded on Monday morning at 0900 or Friday afternoon before a long weekend, then only a couple of taps will break those welds...
Knife point (Kershaw Cryo, my EDC) shows that gap that will be reduced/shrunk to indicate the welds are broken....
There, we got it off and we are just cleaning the threads and splines (3 of them) free and clear of the bead blast grit (the shop class kids bead blast the barreled receiver then parkerize everything all at once)
The piston is there to show how I use a high tech piston alignment tool (aerospace grade, I sell these to you for $50 mailed)....
Oh BTW, we found the gas cylinder lock extended past bottom dead center so we did the 180 Flip Trick and YES , we tightened the gas cylinder assembly to perfection JUST by flipping the lock around. That's it....
I like to grease up the threads of the castle nut before re-assembly:
We destroyed the Xhinese flash suppressor BTW, and I happened to have a USGI unit handy for $75. Now we are placing a dab of grease on the castle nut set screw (always have spares)
Another view of the castle nut set screw going in....
Install or replace your front sight (Zhinese ones require a lot of swearing.... I swear). Grease up the front sight screw... Makes life easier forever...
And finally, a picture to share the precision tools one needs to use in order to work on Norinco Rifles....
Hope this helps you... Always keep spare parts for when you do Screw UP... Remember, it's a Norinco; you can only make them better!
Cheers,
Barney
