  • any chance you could share your valve desgin with me? I'm currently working on a "PCP" semi-auto/full-auto BB and or pellet gun. I would love to know how you desgined your valve! All I can find for valve desgins are the kind that dump all the air in the pressure tank with one pull of the trigger. I think they are called "QEV's"? is this a hammer style valve like used in the crosman 2240? where a hammer of some sort strikes the valve steam which lets only a burst of air through.

  • this is amazing im trying to make something like this but small scale for marbles

  • so how did you made that?
