WE G27 mag won't fill with gas

[joeguitaro]

Hi all, I'm hoping someone in here can help me. I just bought a WE G27. Works great but for one problem, the mag just won't fill. I'm fairly certain it's not a leak. There is no hissing when I fill up or after. There's no overspray. And it's dead silent. When I fill up my WE G19 mag I can hear the quiet stream of gas from tank to mag, as well as on my KJW P226. But I can't hear a thing when I try to gas up my WE G27. On a 5-10 second fill I was at first able to get maybe 7 to 10 shots off. Then I tried lubing the valve o-ring and tightening the valve but this did nothing. Now I'm maybe getting off 5 shots if I'm lucky. Does anybody know whats going on?

Thanks.

Are you using a fresh bottle of propane/gg?

[joeguitaro]

Yes, it's brand new. And like I said, it seems to fill up my other mags fine. I can hear the gas flowing. But when I try it on my new G27, nothing. No noise, no overspray, no hissing. I tried, lube, tightening, different angles, light pressure, hard pressure.

if you bought it from a store id say exchange the mag, otherwise stores like airsoftparts.ca have fill valves for $10ish if I remember correctly

you can also try removing the valve and disassembling it and looking for anything that may be wrong with it, jammed orings/manufacturing defect

temperature can also be a factor, if the mag is significantly warmer than the propane tank, it wont want to take the gas in easily
