Oops, I think. So my story is in order to remove the dimples in the mag tube for a mag extension I used a socket to push the dents out. Worked fairly well but still needed a little more. A friend had used just a dremel on his so I tried that. Here's where the oops occurs. The plug sometimes sticks in the tube, as far as I can tell it's right where the grinding is. I can feel it's a little uneven in there but polishing isn't helping. I'm afraid to grind more because it may just get worse and too thin. If worse comes to worse I'll look into having a gunsmith replace the whole tube. What do you think I'm looking at cost wise and any suggestions?
