mag questions

[underground]

I just got my glock today and its the first GBB i've ever owned but I've been precautioned about the lubing up my mags otherwise it will get "leaky". How would I know if it leaks (besides the smell) and how would I be able to fix that problem if it were to occur?

last question, how would I know how much gas I still have left in the mag. When I filled up the mag for the first time, the gas was spraying very little everywhere probably due to the connection between the mag and canister but how will I know when its done besides waiting 3-4 secs as some have said. Does the gas overflow and does it show it?

You'll know when it's leaking as in most cases you can hear a faint hissing sound, or the fact that your mags end up with no gas in them after storage.

The easiest way to fix a leak is just to add generous lube, either through removing the valve/seal which is leaking and soaking it in silicon oil, or just adding lube through the fill valve when filling or a few drops into the flow valve when the mag is empty. I've had leaks coming from the base mag rubber seal, and all I did was put a few drops of silicon oil in the mag's base crevice, a few drops into the mag reservior by pressing the flow valve open, let is sit for a few minutes, and the leak went away. It's been holding gas for 3 months storage already.

Since you most likely are running propane, follow the instructions included with the propane adaptor and lube the mags as directed.

You'll know when your mag is full of gas once it starts to spurt out around the fill valve when filling the mag up.

You won't know how much gas is left in your mags. What you should know is how many rounds a full charge of gas in your mags can run through from experience; that's basicaly the easiest way to tell how much gas you have left.

silicon oil?

You typically wont need to lube your mags if you use green gas as it has built in lubricant. I've found that if you store your mags with a little green in them, it keeps the seals from drying out which prevents leaking.

Propane works well to for storage just a short burst. And you should always
store mags with a bit of gas in them as the seals will dry up.

thanks for the advice guys I think I read a mag usually lasts about 30-50 shots so I should stop at around 45 to leave sufficient gas for storage (well the next time I refill cuz I forgot to count)

You could fire the mag empty then just put a little fart of gas in the mags afterwards.
Also, I don't think it matters whether you leave a little gas or a lot of gas in the mag - as long as there is still liquid in the mag, the gas is at the same pressure (minus temperature variances), right?

Correct.

However, never leave it with a full charge of gas. With a full charge of gas, it's assumed that while filling your mag, it will suffer cooldown. As such, the PSI of a fully charged cold mag is lesser than the PSI of the same mag warmed up to room temp. That difference maybe harmful to your seals. So for prevention's sake, try not to leave your mags fully charged.
