My problem is, that since installing the insert, first the powertube wouldn't stay screwed on. So I used some blue Loctite. Then, the first game I went to use it again, the brass tip broke off mid game. Fixed that last week. This last weekend, half a game in, the a massive airleak happened. I am going to look at it today to see what's up.
Good thing is, because it's so easy, all I had to do was swap out valves, so it didn't hinder my gameplay at all. And I always bring spares with me of everything. Hoppers and guns.
Automags retired. Enmeys are the successor.
