So when yo guys talk abotu silver soldering on a barrell extension, You mean like sweating plumbing pipe right? I never associated soldering pipe with soldering on a muzzle attatchment.

That is pretty much it, except for the temp to melt the silver solder is much higher. You gonna do some plumbing on your AK? :smile:

I believe 1100 degrees F minimum. Sweating it on with lead core solder could be easily removed with hand tools, ie, a pipe wrench. ATFE wants the extention to be permanent.

Yes, 1100 degrees is the minimum melting temp. Brownell's sell some in a hypodermic type applicator. Just squeeze some out on the barrel threads, screw on the extention and heat to a dull red. It won't work when joining aluminum to steel, though.
