One of the things that drove Jeff nuts was discovering that Cerakote when baked in the oven, cures to slightly different colors depending on how thick the metal part is. So every piece is a slightly different shade. All the mags match, but the gas tube, dust cover, receiver etc are different thicknesses and don't match perfectly. Its the same issue with the SCAR rifles, same finish. I told Jeff that it was just a practical matter with our high humidity Michigan climate and I preferred not to have exposed steel if I can avoid it. A black weapon is also stigmatized in my mind as a "police" weapon, from my youth and it does not blend in well in most hunting environments, particularly after November... Hence I chose the Military Tan. It took about a week for the manufacturer to ship the cerakote order and then it goes ground all the way from WA... That caused quite the delay with the build... We had to figure out which was the most appropriate Warne steel rail to weld to the gas tube, and that was a hassle, since Warne does not publish clear dimensional info on their rails anywhere, so I finally figured out that the TC series of single shot rifles (encore) had a diameter that was closest to our gas tube. I believe it was less that $45 for the rail.
