This looks a cool system for a rifle. It fits on picatinny rails and functions as a grip and a bipod. This would be great if you were operating on a perimeter or behind position of safety (i.e. armored car). Plus, with the multi cam you can't go wrong. But not that it matters, I'm not much of a fan for grips... I prefer to use the magazine housing.
