Eddie has coated a barreled action (complete rifle) and a bolt for me. Both jobs were done perfectly.
Graphite Black is the color you're looking for. My one complete rifle is done in that color. Sorry, I don't have any pics, but it looks great! If I get a pic taken I'll post it for you.
I had my RMR 35 Whelen powder coated and I am very happy with how it turned out and its durability. My new RMR is Cerakoted and I have been advised that it will be every bit as good as the powder coating or even a little better.
If it is as good as I have be told I will likely be getting my CDL done :wink: at a little later date!
