I have a 10/22 that some one threaded the barrel, removing the front sight dovetail. I want a front sight. I did a search and some people said silver solder with easy/soft solder and some said jb power weld. I have done alot of silver soldering to nonferrous metals. no experience with brazing/soldering steel. I don't want to mess up the tempering but power weld sounds weak to me. And if i used solder, I would prefer medium or hard personally. Any thoughts?
