Question to TM Glock 17 owner

No it's a safety feature. Since propane in it's 100% natural form is odourless and colourless you can easily die if there is a leak and you're in a small non ventilated space.

Therefore companies add "bitterants" to let you know if there's a propane leak. BUT that's basically what we *want* in airsoft, liquid propane being transferred to a container (in our case a magazine reservoir) and when the "hammer" strikes the valve shooting a little bit of propane to expand and push a BB down a barrel. Different companies add differing amounts of bitterants but I believe by law they are required to add it.

Best thing you can do is fill it up outside or in a place with good ventilation/circulation (ie. underneath an HVAC outlet/air duct).

Green gas on the other hand has a little bit of silicone oil in it but that's an aside. The "smell" from the green gas (AKA "Girl fart") is somewhat more pleasant but it still doesn't hide the fact that you're still breathing in propane. Also note that it's not horrible for you to breathe it in but you just don't want to breathe in a lot of it. The general consensus is that the Coleman camping stuff is the least smelly (also, mastercraft propane torches too apparently and they come in taller blue bottles which I personally like a lot more than the short stubby ones).

Thanks for the explanations, thats make sense. Will try my mastercraft propane tank from my plumbing soldering kit, the one I tried last night was not a coleman (Ozark Trail brand),

What is the correct procedure to fill the magasine?, I bought the red metal adaptor with the silicone oil side compartment from airsoft parts. I put the bottle upside down vertical then fill the magasine. Tooked approx 6 seconds to completly fill it, but during the fill, lots of propane was release from the adaptor on my finger, it is normal??, does it take another part to get the join between the magasine nozzle and the adaptor nozzle?, now it's metal on metal, don't seams to be seal during filling... or maybe I do something wrong??

thanks

Yeah you're doing it wrong. I did it that way too but once you can get the hang of it you'll have minimal leakage from the propane.

Basically like this: YouTube - Filling a Gas blow back mag

Note the first one was good and the second one not so good cause you can see the liquid propane not going into the mag but instead leaking out and "sublimating" into propane gas. Also of note is that once the mag is full of liquid propane it will start leaking out too as it's supposed to be a safety feature or something.

Yeah you're doing it wrong

What I did wrong?, I do the same way as the video, bottle in this position,
as the magasine fill, I can feel it came really cold, it is normal?

I tried this morning with mastercraft propane and yeah the smell is less than previous tank i used.

I got this mastercraft tank from about 7 years ago, use it many times for soldering.

this morning i have filled about 5 magasines, and after it seams that the pressure of the tank was not enough to fill more magasine, no more propane wants to goes into the magasine.

I can still feel that there is propane in bottle when shaking it, but not that much.

So I conclude that we cannot completly empty a propane bottle because the pressure drop as the propane quantity drop too, is that right?

how many magasine can I fill with one NEW mastercraft tank approx? This will give me an idea for my next new bottle, if I do not loose too much propane.

Thanks again!
