If you have a threaded barrel and want to make it compliant for a Ban state- is there any epoxy/glue (black loctite?) which I could use that would qualify a break as being "permanently" attached?  I'd rather avoid the welding/drilling and tapping method.
Thanks

It must withstand a certain temperature to be within most 'rules'.  Brazing, or pinning/welding are your best solutions.

BATF's interpretation of permenant is either blind pinning or any welding method that requires getting the barrel over 1100 degrees to remove.
This rules out the low temperature 600 degree silver solder that you can put on with a propane torch.
You have to go to acetelene or mapp gas and 1200 degree silver solder.
I really dislike getting a barrel this hot, it takes away all the heat treating and stress relieving that the maker of the barrel does during the fabrication of the barrel blank.

I much prefer a blind pin and that's how I always do it.
