Harley, I don't recall if this version of KWC rifle has an internal gas reservoir (the solid stock version does, I might look into that), but have you tried 134a in this gun yet? I might purchase one, and am looking into an external CO2 rig (I have a few LP regs lying around from my paintball days) with a 9oz tank. If I were to run out of CO2, I'd have to have something to fill in, hence the 134a. Green Gas is too expensive for me right now <img src=icon_smile_sad.gif border=0 align=middle>. Could you possibly try this out and let me know? I would really appreciate it. If you don't have the internal reservoir and can't use the Green Gas rig, therefore you can't try this, that's fine. Never hurts to ask, though. Thanks!
Nick R.
