Why do mags leak out the back

[Stinger]

I really hate it, my mag and others I use leak out the back. It drives me insane!!!!! I know how mags work and stuff and have been shooting them for years but I am at a loss as to how to make this stupid thing stop leaking.

It's the pressure relief port for the reg. To stop the leak, reduce your input pressure, or get an HPA spring pack (If you have an old mag, pre CF28000)

Also try cleaning or replacing your piston o-ring, mine was dirty and it caused my mag to leak out the back, but i wiped it off and its fine now

Turn your velocity down... :)

[Coaster]

is it a leak or is it venting?

[Stinger]

I clean it religiously, and of course turning the velocity down came to mind lol. would a preset pmi tank be putting to high of preasure into it, they are set at 800psi. I wouldn't imagine thats it but maybe.

Throw 4-5 drops of lube in your airline...then tell me what happens

Worked for me every time! :cool:

crosswind fans to keep you cool????
I don't get

of course I tried oiling it, no help, I've tried all the regular things to do.

You don't understand, it's merely a feature that cools you off on hot humid days. ;)

If you mean the velocity adjuster part try replacing the seal inside the reg. Mine fell out and caused the mag to leak like that.
