Yet another whats wrong thread ...

 

I have an Extended mag that i've acquired for a couple of beers, but it has an issue where,  it either just vents its gas on first shot or fires a couple of shots then just vents it all out, Mostly the first.

 

0 issues with my standard mags which have had 100s of rounds through them, so i'm not instinctively thinking its the hammer, yet.

 

Already replaced the output valve (and O-rings) with a new one as i figured, it was probably that to start with and for the sake of a few £ it's worth a shot but no joy.

 

I use Green gas in all my magazines, WE 18c gen3, Guns lubricated and the only modification to it are a Maple Leaf hop unit and barrel.

 

Any idea what to try next?

 

Could the choice of gas be an issue causing it to be out of battery or reset the hammer?

Check the outlet valve on the mag, may need a strip and a lube. Could be sticking a bit and allowing venting. Had the same thing with a GBBR mag a while back.

Rest the mag on something solid, or hold it in with your hand tight around the grip/mag interface, see if that helps

 

thanks for the suggestions, what would I be checking for? If this is the solution? The     Seal around the gas route rubber?
