Bad air leak

[FiveYearMagUser]

I have had an automag for five years now, and this is the first problem wiyh it that I don't know how to fix. There is an air leak coming fom between the main body and rail. I have had a BOO-yah frame on for about six months now. Is the leak coming from the valve and if so what do I do, please help me!!

it may be leaking out of the two oil wholes in the bottom of the reg. i had that problem with my mag a few years ago and some oil fixed it.

If you noticed when you put the new on/off valve on with the boo yahh it had a crappy black o ring on it these suck mine leaked from there very slowly so I replaced that seal it fixed it I'm geussing it has something to do with the on/off If you hold the trigger down and it stops leaking it probly isn't that if It leaks regardless of where the trigger is then probly so
