What additional stuff is needed? The bipod simply switched places on the rifle. Only addition for that is a couple small rail lengths. The flat side of one of the wedge-lock blocks will work as a standard barricade block. So, what is left to carry around? A second 2 oz wedge block that fits in your pocket.
Also, most of the tricks with bags that were demonstrated were only using a single cylindrical soup can sized rear bag (Coretac mini Corebean) that most would already be carrying as a rear bag.
