I've taken apart and put together my pro/carbine's CVX valve. So, I'm not afraid of modding valves. The splatmaster's valve looks like its a matter of screwing off the face of it. If I were to clip the valve spring, would that increase the volume of air released with each strike?
Using the barrel as the hammer... what a crazy design. It would interesting if someone could interview the designer(s) of the splatmaster and find out what they were thinking?
