Ah - I see your question now.The barrel & breech are almost 1 unit so I don't think there's anything you can do there. If you can separate the barrel, does it fit the phase 2 breech?
The valve & tube can be aligned if use a punch and rotate the valve but it looks to be "in spec"
How do things look when you fit the transfer port seal in place? There is some room on the barrel and tube for the seal, so there's wiggle room for alignment. Make sense?
You guys have any advice on what to paint the aluminum grip frame with?I can tell you that the high heat paint from Ace Hardware doesn't work.
