I've got a 30-06 BAR and I want to change it to 6br. Trying to find a smith to do it at the moment. Kinda bummed nobody makes a 20 moa rail for it but the Vortex 5-20x50 kinda deserves it. Thinking I can use a Caldwell brass catcher from an AR but I might fashion something else as those Caldwell's look stupid.
