When Airing my gun up...

[pbsnor]

I have an E-Mag that I just bought at the begining of the summer.. standard valve that it comes w/ but a level 10 installed for the bolt. I do have an on off on my drop.. So I screw my nitro into the drop then screw in the on off (its a benchmark) I was just wondering that why when i first screw it in, my gun shoots out air from the back of the valve and it makes a really loud noise either till i unscrew it or screw it in the rest of the way.. (seems like it is different every time) I was just wondering if it is SUPPOSED to do that.. or if sumthing is wrong.. and if so, what might be wrong? I figure if that isn't supposed to happen then it might be an oring or sumthing sumwhere...?

oil your valve and try that, if that dosent work turn down the velocity, if that dosent work, check your orings in your valve

EDIT : oh your not shooting your gun are you? check your regulator o-ring i think it is..

Sounds like your velocity is too high, or an o-ring in the reg.
