My grandfathers' old quote; "Shiny things on your gun are in the same category as the nickname 'bomb magnet' was given to aircraft carriers in WWII."

Got my new CMMG 16" 308 upper, very nice, the barrel is Stainless but it is too shiny. Way too purdy for my ugly arse.

"Other" than replacing the barrel, just in case that was the suggestion, anyone else have a similar problem with their purdy toys?

Is there a coating that I can paint on to cover it up and withstand the heat, literally?
