I made a barrel removal tool out of leaded steel (12L14) and unscrewed the barrel by the rifling. The setup consists of the barrel, the big part of the shroud, the muzzle brake that is the barrel nut. The tricky part was I had to torque the barrel in place by the muzzle brake/nut, then disassemble it and machine a little off, then re-torque it and keep doing that until the end lined up perfectly when tight. For extra safety so the brake cant unscrew under recoil (twist) there is also a pin that goes between the 2 parts and a setscrew that adjusts pin depth but totally inside the heavy lug and not visible. The screw is accessed from inside the ejector rod slot in the shroud. I can add a picture eventually. This is not meant to be changed quickly in the field like a Dan Wesson. Although I can take it apart it is meant to be a more semi-permanent assembly.

Thank you. I drew up the end mills I wanted with a CAD program called EZ CAM then I submitted the drawings to a local cutter grinder. He was nice enough to grind up my cutters out of some old end mills he had laying around, saving me a few bucks. They are solid carbide and the material for the main shroud is 17-4 stainless so they did get a little bit of chipping by the time I got the depth I needed. The finish milled profile had to have a ton of hand finishing to get the machining lines worked out to where it looked nice.
