And a similar problem with the bottle being pushed up with the stock screw tightened. I had to text him to remember but his bottle wasn’t screwed all the way down (1/16”) out. When he tightened the bottle down the issue went away. I don’t recall the specifics as to why. I was there when he discovered it. Just throwing that out to you as a possibility on yours. Sure seems odd. Hope that you get it worked out. It’s a bummer to spend that kind of money and the gun isn’t perfect.
