Saw this thread on AR15.com. He did a great job. Makes me want to try it myself. I'd have a hard time painting a "nice" gun but a wally-world ADL....maybe.

The Mcmillan stocks on my predator rifles are already dark camo, but the SS barrels and the scope and mounts get painted to remove any hint of glare.
