I really love my AR's, but I know I will never be selling them, and all they are is tools really, so it didn't bother me to paint them. I just used the rustoleum ultra flat camo type paint. of course I cleaned all of the oil off the rifle first. I know that looks like black in the picture, but it's actually olive drab. i only wanted sand and olive drab in the color scheme, so i just covered over the black with the sand.
