Alright Uziel, I got 2 questions for ya. I just bought a 45/45 HPA/Comp-Air tank and im wondering what I should do so I can get the most shots of of my tank? Should I adjust the screw at the bottom of the reg? adjust the dwell? of something about the LPR? (I don't know what that is). And I was wondering is the New Designs bolt that increased your velocity so you can decrease your pressure or dwell is really worth the money?
