What confuses me on chassis like this is the idea of bringing in AR-15 ergos to a chassis, specifically the grip. When you look at the pistol grip and the machining above it where the web of the thumb would go, it looks like it is meant to be gripped like one would an AR-15, with the thumb wrapped around the bottom to where you would actuate the safety/selector on the left hand side. When shooting a bolt gun, I want my thumb either on top (traditional rifle stock) or on the same side as the rest of my hand for bolt manipulation. I don't know anyone who shoots a bolt gun, and then re-grips the gun like an AR between every shot. I see this chassis, and it begs for a new grip set up or at least a thumb rest.
