Another Noobie style question

**Villain** · 07-01-2010, 12:32 PM

Ok boys, Ive been running with a 1911 blowback pistol for a little while now, but theres something I never could quite figure out; when filling the mags with green gas, how do I know when its full? I always just put a whole buntch in until I thought what I was doing was excessive, is there a trick to this? I did search for this in the forums but didnt find too much. Thanks in advance.

What I do with my M9 mags is just put my ear close to the mag and listen. While filling, it will make a loud, "sssssss" noise. When it starts to become full, that noise gets starts to quiet down considerably.

May or may not work for you. If it doesn't, then usually just a 3-5 second burst of gas is enough to fill the mag.

I've always done three five second fills. I've always gotten atleast and a mag and a half out of a single fill doing it that way.

But how many times do I do the "bursts?"

I think he meant three, five second bursts.

Yep, do a five second burst three times and you should be good, worked for my WE's, TM's, and KWA's.

When there isn't that much ambient noise, I find that listening to the hiss works. Otherwise I give it a good 5-7 second fill.

Somebody needs to invite a little tiny guage thats pretty much idiot proof.

what brand is your blowback pistol?

if it's a WE or KJW, it will have tiny orings in the fill valve that prevent gas from escaping as you fill it. it creates a seal between the fill valve and the propane adapter (or tip of the green gas can)

If your magazine has those o-rings, you can indeed hear the gas being transferred from the propane tank to the magazine. when the sound stops, the mag is full.

if your magazine does not have an o-ring in the fill valve, then as you fill the magazine you can hear the hiss of the air being displaced, rushing out of the magazine. You can tell when the mag is full because you will begin to see liquid propane squirting from the fill valve area, and the sound will change.

I hope this helps.

Thanks for the help man, its a WE, so Ill do some trial and error ****; but I still stand by my previous statement, just put a guage on the frickin thing.

I'm pretty sure all non-CO2 gas mags have O-rings in them, otherwise the gas would pour right out in seconds
