He's exaggerating... a bit... you can't use all of that potential at 30 bar with no firing mechanism and such a short barrel. I think you'd see a bigger improvement by speeding up the ball valve with a spring instead of increasing the pressure. my next gun will have a qev and a longer barrel althou...

Don't bother pumping above 3 bar or so, before you´ve opened that ball valve the dart will be long gone.

really? it gets more range with more bars at 17 normal firing pressure it goes 120 + meter

this is my first rifle (that works!) it fires homemade darts at a max of 30 bar pic here the gun http://i286.photobucket.com/albums/ll118/jblaterfire/IMAGE_001.jpg sight for the show :shock: http://i286.photobucket.com/albums/ll118/jblaterfire/IMAGE_002.jpg 28 bar can go further http://i286.photobuc...
