Velocity Problem NOOB

[magman111]

hey guys i just recently got my mag in like 1 week ago and it was shootin fine.
my velocity was at 284 which is perfect but this sun there is a touny whiich only allows 250 and below.
i took the gun home and i have no air left but i decided to mess with the velocity screw in the back of the valve. But when i stick the allen wrench all the way in there its not tighting or lossning. Is it only suppose to work when theres air put through or wut???
thanx guys

No you can move the velocity adjuster when its not gased up, but dont mess with it when you dont have a chrono. what's the point? P.S. counterclock wise lowers velocity

if it's brand-new, the adjuster nut oring is prolly a little tight, nothing to worry about

Ya. Likely it's just tight. I'd reccomend when you get a chance, WHILE THE MARKER IS DEGASSED, take the nut out, and put a little lithium grease on the threads of it. My RT was fine in this regard, but my friend's needed a little grease to help it out.
