Most USG's I've seen were grey

There was a limited run made with black controls.

Someone could have changed the controls to the black ones.

In all honesty, I don't think the 16" barrel looks bad at all, I might even prefer it aesthetically to the SBR. I certainly prefer the velocity gained with the 16", you really loose a significant amount of velocity cutting the barrel down, and definitely sacrifice some armor penetration. From the videos I have seen, the 16" will get through things the SBR length won't.

There is only about 200fps difference between the barrels. And the short barrel came along way before the long barrel did and looks a whole lot better.
