Try replacing the o-ring on the tip if you haven't already. I was having similar issues with bolt stick and double firing on a mag last week pulling my hair out trying to swap out every part to trouble shoot before I ran out of air. The power tube tip not staying tight was one issue I ran into swapping out different spacers. My issue in the end was the body was refinished and polished where it met the rail and the tolerances were out of whack.
