This looks like an impressive gun to me. The idea of having to change mags and not having a straight 200 balls to shoot makes it seem at lot more about skill rather than shoot and run. but this also can run without a 0.8 or 1.1 air tank. easily changeable 12 gram cartridges takes around 30 balls per take. anyone used or know of what this gun is like? And is it worth playing with 12gram cartridges or just hook it up to remote line?
