when i was playing today my mag would get major shoot down every other time i shot. I wasnt short stroking the trigger, and i replaced the reg seat and the orings in the on off. THen the tank never did screw as far in as it usually does, but it shot fine. Then i took the tank off and when i went to put it back on it went as far in as it usually does, but does the shoot down every other shot, the ball barely comes out of the barrel....sorry for typos i am in a hurry.
