Heard you can do with dremel tool and special attachments. What do I need as to polish and attachments for the dremel?? I think this will the problem I am having. As well as make the barrel look awesome.
I polished my feed ramps with Flitz which is a good polish used for aluminum aircraft, very fine. Since I don't have a dremel, I just used a piece of cloth and something round, like a pen. More elbow grease, but very controllable.
If it is under warranty, send it back first.
