If you can't build your own, take the bolt to a machine shop which can and explain what you need. If the shop is CNC equipped, the first one might cost a bit but the next guy who needs one will make out OK! In the early years I made a few wrenches with just a single lug for three-lug actions (Wichitas) and they worked fine but we didn't cinch up BR barrels all that tight anyway. Today, I make wrenches with all the lugs and for various actions (Barnard, Sako, Browning, RPA, etc.) but only for myself and they are ok too. GD
