Most guys use a dremel with cratex polishing wheels, but having a $600ish barrel, I went the manual route. Find a small dowel or round rod and wrap sandpaper around it starting with 600 and working to 800,1000,1500,2000. These papers can be found at auto paint suppliers. If you can find a tapered rod it works better. A 5.56 case tapped on the bottom for a 1/4" bolt would probably work great. Just work slowly and take short, even strokes. I don't have pictures, but I never have scratched or gouged brass. Also, polish the inside edges of the feed lips on your mags. Those babies will gouge brass pretty deep. Disassemble mag and try to put a SLIGHT bevel on the inside edge of the feed lip. Again, work slowly. Hope this helps
