Have any of you guys permanently attached a flash hider with +1,100 degree silver solder? Here are a few products from Brownells that look like they would get the job done.

I like the idea of being able to do it myself and being able to change a FH without destroying it. I just wonder why I do not hear about more folks doing it. Cutting off a Phantom would not be too expensive but a Battle Comp or an AAC mount/FH is kinda expensive to be throwing away. The solder looks easier and like it would look better. Do people pin because it is easier to visually inspect the perm job? Is there risk of damaging the rifling?
