Long story short, fleetingly industrious relative installed a pin on muzzle brake to a Norinco match Mak-90 with JB Weld without accounting for gravity and the relatively loose fit of the brake while it dried. Now Mak looks like a sure candidate for Viagra. It keyholes ~3 feet to the left at 25 yards and develops an increasingly shiny, polished copper mark on the mouth of the brake. I enjoy projects, especially those firearm related, so I'm going to consider this an opportunity. I also end up shooting the piece a good bit so there's the rest of my personal interest. The two ideas bouncing around my brain have been: 1. I've heard you can heat JB Weld up to a certain point at which it might release so that I can reset the brake properly. I'm posting here to figure out if I can learn how to do that without ruining the barrel or if I ought to stop here and pay my favorite gunsmith to let me watch him. This would be more aesthetically appealing, i.e. no more limp bizkit effect. 2. Bite the bullet and use my mad Dremel skills to carve a path for the bullets to go. How hot do I have to get the JB Weld to release and compare that to how hot I have to get the barrel to permanently damage it? What would you do?
