I asked local gunsmith , who is a great guy , if he could thread my barrel for a flash hider. He said he could not fit the barrel and receiver in the lathe. So he suggested to ream out the flash hider and tap it on over the barrel and drill 2 small holes and insert to small screws. The flash hider is about 3 inches long and has about 1/2 inch thread.So it would only go on to the barrel 1/2 inch if threaded.There is a raised ring around barrel about 1 1/2 from muzzle , so I suggested maybe we ream out flash hider 1 1/2 so it buts up against this ridge. Any body think that this will be ok. My only other option is to ship rifle away.
 
When I had mine done, Josef Dlask machined a spacer for me that filled the gap between the ridge and the rear of the flash hider. It made it look really nice. The barrel was threaded with the proper amount of thread for the standard flash hider, and the flash hider didn't look out of place due to that gap.

Since I don't have my POS SU-16 anymore due to the receiver cracking, I'm willing to give you this spacer for free if you want to do the same thing.
 
First thanks for the reply. I understand what your saying.But if it is milled out to 1000 th of a inch and fit on the barrel nice and snug , would it interfere with the accuracy or weaken the barrel?I like the idea that it will fit further on the barrel. Isn't the flash hider mostly for appearances anyway in regards for what I'm using the rifle for.......target shooting and coyote hunting. I'm in NL and nobody here can thread the barrel , if I had to send it to BC ,it would take months, it took 21 days to get somet
Hing from Calgary one way lol.Anyway I have until tomorrow to decide.And thanks all stone I will let you know tomorrow?

Yup...let me know. I think that the nicest way to do it is to properly thread the barrel, and then use this sleeve that I have which Josef made. The caveat here is that I don't know if that will affect your rifle's warranty or not...assuming that you bought your rifle through a legitimate retailer and it does have warranty. If you bought it through the EE, your rifle is not covered under any warranty, and you're free to do whatever you want.

By the way...I'd worry about that plastic receiver sooner than anything to do with the barrel.

yep bought it on the EE . The receiver looks to be some kinda white metal .Appears to be cracking where white metal is joined, maybe there could be some way to apply small layer of black rubber coating over that part of receiver to absorb the shock of the pin that is hitting it. Something like that spray on box liner matarial applied on outside of receiver , just a thin layer.

The upper receiver of the SU-16 is all polymer as far as I can remember. The problem area is the back of the receiver where the bolt is designed to slow down and impact. Here's the pic of what happened to mine...

Not very many rounds through it either. There's not going to be any negative impact on your barrel by just having something slid and attached over it. It's just nicer to have it threaded for muzzle devices, that's all. The less money you have into it, the less money to be potentially lost.

That broken piece looks black all the way through,I've seen a couple from google search and they look silver or light grey on the inside which looks like white metal to me ,also mine feels like white metal to me . Like white metal with black paint.My gunsmith said it appeared to be white metal also.I will find out for sure.Im going ahead with ou threading barrel,will use some kind of locktite and set screws and may be a some kind of weld. I don't care if it's pernament.
 
Thanks to all for the input from all of the opinions and all of the Google searches are done I decided to go ahead and have the flash hider put on the rifle without threads and am on my way to the gunsmith to pick up the rifle now
