Leaky KSC USP Mag.
 

I did search around and found a few helpful things, but I would still like a little more guidance.

It's leaking from the top of the mag, where the gas comes out. I learned how to take it apart and applied a little silicone oil to the o rings in the valve that screws out. It's better than before but still leaking. I'm wondering if I should take the o rings off and soak them in silicone oil or maybe soak the whole valve apparatus in silicone oil.

Any help is much appreciated, thanks.

I realize that this is a common problem that most of you probably hate to repeat answers to, but I could really use the help. Thanks.

Don't take it off, just soak the valve completely in silicone oil 1 hour.

you can find all the answers regarding a leaky mag in the "gas gun solutions" section as well. And as mentioned by Splash, your best bet would be to soak the o rings in silicone oil.
