ok, apparently alot of tech's and airsmiths have been telling people with regs on their markers that you adjust the velocity by the reg's output pressure;

AHHH!!!!!! that is the #1 way to make you marker have terrible effency and velocity probs. You adjust the velocity through the markers velociy adjuster, NOT THE REG!!!
if you are having velocity probs, put the adjuster screw near to all the way out (lower velocity) and slowly increase the pressure(keep shooting while you do this) until you get good velocity.
tell every1 who thinks the opposite that they're wrong!
thank for the time
