I recently purchased a 18" fluted stainless heavy barrel for my 10/22 build and I was somewhat surprised when I opened the package. It'll really dirty/dingy looking. My factory barrel was a nice clean stainless, the compensator I ordered for this build was clean and shiny, but this barrel wasn't. It's a darker grey looking color more than stainless in my opinion and even the markings of the manufacturer look pretty cruddy. What should I use to bring a higher shine to this barrel, and is this pretty common for the Green Mtn barrels? Will edit with pics when I get back home tonight.
