So my brother gave me a Vortex flash hider to put on my M14. He had an extra for his AR(.223). I thought I read that it could be drilled out and threaded to fit a M14 but can't find it. True?
 
Typically, it would be the Norinco barrel that is altered to allow for the flash suppressor to be installed. It would be turned down on a lathe to 1/2" and threaded to fit the suppressor. Maybe there is another way, as the Norinco barrel does have threads for the metric nut that holds the existing flash suppressor in position, but you'd have to tap threads into the flash suppressor in that obscure Norinco metric thread, and live with the unsightly splines that are rearward of the threads on the barrel showing. Of course in any event the suppressor itself would have to also be bored out to allow for 30 calibre.
 
I have a question . If a USGI castle nut can be carefully threaded on to a Chinese barrel ,(it can ,I have done it).,then why can't a Smith vortex be threaded on to a Chinese barrel the same way ?
 
If I had time, I'd take a picture, but I have a spare barrel here in my hands. There are threads out near the muzzle, then after that (nearer the breach) another section about an inch long that isn't threaded. There are three flutes (channels) down the length of the threaded and smooth section of the barrel I just described. Into those flutes the stock flash suppressor slides and is indexed. If you thread a muzzle break (custom made to fit the Norinco metric threads) and just screw it into those threads, you leave open the flutes. Maybe it spits flame and muzzle blast right back to you, or it doesn't, but that doesn't seem like a good scenario to me. You certainly wouldn't want to screw a muzzle break on like that, it would blast right back at you down those grooves. A flash suppressor, not sure what would happen, but I'd certainly want to have safety glasses on.
 
The AR vortex is 1/2 28tpi, the dia of the barrel of the norinco is about 9/16, and I believe the end of the barrel where the flash hider currently sits is larger yet, it will have to be turned and threaded. I chopped mine at 18 1/2 inches, re threaded and put on the new brake, although I used the navy style instead of the vortex.
