It is probably a dry chemical fire extinguisher then. I recently acquired one and it says tested to 360 psi. But it feels rather thin. Check the label, if it's a c02 fire extinguisher then it can hold quite a bit of pressure. And of course, you could always epoxy a nipple or thraded fitting into it if you are good with epoxy.

Yeah, it's that important.

I'm pretty sure it said dry chemical. I plan to use only 150 psi though. I decided to connect it to the gun as like a stock, that way I don't need a backpack and go through the trouble of a hose.

Well you wont get very many shots out of the bottle. Even if you have 4 attached together you would only get a few shots out of the whole thing.

My humble suggestion is to get a c02 or hpa tank and a reg of sorts. I too tried to make my own portable airsource but the truth is, with such a small chamber you'd need very high pressures to have the kind of effect you are looking for.

It is for a bbmg firing in very short bursts in airsoft battles lasting under 2 minutes. I may mod two of them with quick disconnects in case I need to switch them out. The last thing I want to do is get CO2 or HPA and a reg. Way too much money for me. Not worth the little airsoft wars in my backyard.

he plans to make a BBMG. I have not made a BBMG yet, but when i hooked my FE up to a blow gun i got a solid 13 seconds of firing. this was achieved with a flow control unit, but still, it should be suitable as a side arm in any airsoft match. I would recommend a backpack tank to supply your stock tank in case of emergency.

You got 13 seconds how? With a regulator? Well, I may be in luck with that, I might be able to fix the broken one on my compressor because we just bought a new one.

Yes I realized that, but even so BBMG's need a lot of air to function properly and quick bursts can still take a toll on a small air chamber like that fire extinguisher. Have you ever thought of using propane like Insomniac? It's cheap and works really well, it just smells bad.

technically it is not a regulator, more of a flow control valve. its pretty much a ball valve that has a wheel instead of a handle, and you can adjust it precisely. its a pain for filling up cannons, but it works perfectly for BBMGs

I don't think my dad would let me use propane. I want to try the fire extinguisher and see how it works. With the regulator and the fire extinguisher pressurized to about 160, maybe I can regulate it to about 90 and get a lot more air off it. The regulator has a gauge to 200, do you think I should go near that? I think the highest I can get with my bike pump is a little over 160.

Please remember that the Test pressure and the Working pressure are not the same. When filling to the Test pressure, it is filled with water and placed in an explosion proof cage. When filled with air, it is filled to the working pressure and hung in public places and does not require protection from accidental bursting. Keep this in mind when building things using tested pressure vessels. Failure use them safely can result in death.

Test pressure is a pressure it might not blow up. Working pressure is the lower pressure where there is very little chance it can blow up.

Don't worry, I wanted to test it for at least an hour fully pressurized.

Oh its a gate valve. I get it, but a regulator would be more effective.

Cool mine is just a 22 dollar standard one. If I can get it fixed it will be a life saver.

EDIT once again, do you think it is safe to use a reg at 160 psi? The compressor it is used on can do 150 psi and the gauge on the reg goes to 200.

That is a gauge and a flow regulator valve .

It is not a pressure regulator.


OTOH if you are filling a chamber from a high pressure source, you can feed it slowly and stop when the pressure is reached.

So what is the difference between the two?

Yes that is true. You would need a gauge on the gun though. This is for a bbmg, so my best bet is to regulate high pressure to flow straight into the gun.
