reg leak

[brazen serpent]

my reg on my mag is leaking through the hole in the velocity adjustment knob [the hole where you place the allen wrench to adjust the velocity.]

You might try replacing parts in the valve (o-rings etc) and/or lowering your velocity. If these fail, you may have to replace your reg piston if I remember properly. I'm sure someone else will try to help add on to this soon. =)

Like centerfire said, most of the time it is due to your velocity being too high. Your reg-seat could also be bad. And in the most extreme case, your reg piston will need to be replaced.

Before you buy any replacement parts..try replacing the reg piston o-rings... get a rebuild kit and slap them on, I've never heard of them going bad..but hey anythings possible. If that doesn't fix it...at least you'll have a rebuild kit when the time comes :)
