I have seen enough game spooked by shiny rifles that I paint everything with Rustoleum Camo flat spray paint. Usually my scope as well. If I ever decide to sell, brake fluid and some very fine steel wool cleans it up like new. I repaint every year, because it does scrape off, just like the anodizing did. Rustoleum also makes a Textured spray paint that I use on things like shooting sticks and black gun stocks. It is the best camo spray I've seen. I was once watching a buck when some hunters came up the canyon with their shiny barreled rifles glinting in the sun. When they were still a 1/2 mile away, the buck moved behind a juniper bush and stayed there until they were long past. I waited until he came out again and shot him. I've watched the same scenario with aoudad sheep, except with no place to hide, they ran for miles. If anyone has tried the aluminum black, I'd like to hear their results.
