This might be a dumb question but if I was to have a barrel threaded, chambered and fitted so the headspace is indexed to the face of the barrel to the shoulder of the action rather than using the barrel nut (i.e. 700-style), how would the recoil lug be attached? The barrel nut fixes the recoil lug to the action so if no barrel nut, how would the recoil lug be held in place? Or am I thinking about this all wrong?
