GHK c02 mags M4 leaking

[Jez Armstrong]

Has anyone had an issure with their c02 mags?

my GHK ones have leaked since i got them second hand, the previous owner had told me they are an easy fix and so far they have not been, ive stripped them right down and silcon greased them to death and without replacing o-rings im about ready to throw them in the bin

also before anone replys with "buy the G&P ones" they are on my list of things to buy when i dont have to pay for life!

any help would be great otherwise i have a £500 WOC thats going to live on the shelf
