Hey everyone, I plan on buying a Coyote Brown ACR. I've been looking at a lot of different pictures and I noticed that some ACR's look like the upper and lower are different shades of brown. So here are my questions. Do all ACR's have a different color upper and lower? Is that a option some people choose? Or is it just luck of the draw? I plan on buying online that's why I'm asking. Any help on the matter will be greatly appreciated, thanks.
