Gator, I'm sure the mods I did to my tube would lend itself to the Galatian quite well, but that is only part of the story. You would need to port the rest of the rifle in or around where I did to fully exploit the power. Needless to say I don't have any fancy tools like a lathe or mill to do any of the work. I mostly use a numbered drill index , a drill press( like Harbour freight quality),of course a dremel rotary tool and a few measuring tools( vernier calipers and micrometer). I should make a video on how a caveman would machine steel parts. It's quite the process , would make a machinest cringe. Lol
