I'm trying to remove the mag tube on my mav and thus far all I've managed to do is scratch it up... What are y'all using to melt the thread locker? I used a lighter, and even a gas grill. I put a pair of vise grips on it and it wouldn't budge. I tried to use a rag between the teeth but still f'd up the tube a little? Are y'all just heating to where you can see the threads or are you heating where it says made in Texas too? What am I doing wrong? Sucks I scratched up my gun for a $25 part..
