Call me crazy but when I picked up my SCAR 17, I had a choice of the FDEdark earth or black. The new tan or dark earth appeared to be almost multi colored with a green tint.
I got the black and love it!
It is not crazy at all. Kaleidoscope Darke Eyrth is inherently less accurate due to the different parts heating up at different temperatures during firing and causing uneven warping of the upper and lower receiver, constantly changing your POI and causing massive fail all over the place.
