^^^ They didn't have to do much work - ACUs didn't work worth a damn in Afghanistan, and Crye Precision developed the multicam for them, and put it on people.
Basically, they had someone move the colors around a little, or make subtle changes to Crye Multicam, and called it their own - without a doubt to avoid paying CP for the design.
Same exact $hit they did with their "new, improved" mag followers. Make a change, call it your own, and don't pay MagPul for the design.
They probably STILL paid too much.
