Major mag problems

[Automager]

Ok, i went out to play to other day. I gassed up my mag fired like 10 rounds over the chrono, my crono read 120, 290, 365, and 390... The gun also is making a farting sound out the back rear velocity, and during play it starts leaking out of the back... I NEED HELP...

co2?
anyway, sounds like your reg pin is sticking, or your reg seat is leaking. the leaking out the back is over pressure release, it will do this anytime the pressure in the reg gets to high. try getting an agd prts kit and replaceing the reg seat oring, theres a strong chance this will solve your prob.

CO2 might be your major problem. The reg. pin and seat are good was to go, but you might want to look at the reg piston also.

Velocity trouble = Reg seat
