JB and heat
Some of you may have seen my most spectacular shot last Saturday, when I almost took out a rimfire swinger array about 30 yards downrange with the flashhider/front sight assembly from my Mini-14. Had to ask Jason to call a ceasefire while I went down and retrieved it. The flash hider and sight is none the worse for the experience, but the setscrew will NOT be trusted to retain it in the future. It appears thet some type of adhesive was also used on the bearing surface (the thing was on the gun when I got it) and the heat of firing a number of rounds caused the adhesive to fail.
Thinking of using J-B weld to reattach the flash hider. I know the stuff is strong, but does anyone have a feel for how J-B stands up to extreme heat? OR, does anyone have an alternate suggestion for a permanent reattach, short of having it silver soldered on?
