G39 Mag Issues

[Jacob Wright]

So yeah, I try to charge it. If I put the gas in for more than 2 seconds it vents from the valve or somewhere else.

I've stripped it down and lubed all the o-rings but it holds enough gas for 5 shots and stops.

Can anyone help or should I just get a new magazine?

Many many we Mag have a same problem- can not charge it full. You can put the mag in refrigerator for make it cold.Then charge gas 4~5 second. Finally make it warm. The mag should be full.
