I have a BAR-10 that I got a couple months back and it's still stock. Great rifle by the way, but I stripped the allen screw that holds the receiver to the stock. I tried super gluing the allen key to the stripped screw and twisting but failed epically. I don't have access to a dremel and I have no clue how to get it out. I really want to do the airbrake mod and clean the internals, but I can't. Help?
