Leaking

[Hellsman]

Hey, I have a Minimag and where you put the alan wrench at to change your velocity in the back is leaking on me, but when i turn it to a certant point it stops. Any ideas on wat can be causing this?

[sicones]

It automatically vents when the velocity is too high.

Is that the same with regular automags too?

Yes.. all AGD valves have a pressure safety funtion that vents excess gas out the back when the pressure is too high. This is to keep you from cranking the gun up to like 400 FPS!
