I get the point in their bolt knob - watch a PRS guy guy run the bolt sometimes - they like to come up with that right index finger to initiate bolt lift, while keeping the thumb to the right of the pistol grip area as well - providing a small valley there to do so - its an idea about that work I guess. It's not for me tho, like the look of the KW shifter. Local gunsmith has built a couple Mausingfields and I saw one - seemed decent.
I do like that they are offering the ARC bolt head size.
