Running Co2 on NBB and GBB guns

[Dog Face Killer]

Has anyone used or tried to use Co2 on ether a GBB or NBB stock mag. Please post your thoughts and or results.

Boom

mag, sure, it'd work

your slide on the other hand......

that, and CO2 (or black gas) is a lot more powerful than Green or White (Propane and duster, respectively) and will significantly increase the wear on your gun, and the ire of your fellow players when you use it at closer ranges.

What gun are you thinking of using this with?

[Dog Face Killer]

well... im thinking that there is a way to regulate the amountof pressure when filling the mag...soo... you would be able to dictate within reason how much pressure you are using to fill. i would use it on my G23F... fully upgraded mind you.

Can i ask why in the world would you want to use Co2 in your glock?

[Lokes]

what would be the point? going to great lengths devising some way to regulate the pressure when you can simply use duster or propane.

CO2 equilibrium pressure at 20C ~ 800psig
propane eq' @20C ~ 115psig
HFC134a eq' @20C ~ 70psig

800psig requires well engineered failsafed containers. Cast aluminum mags are pretty far off from safely storing CO2 compressed to liquid.

I have used CO2 regulated to 250psi for a custom shotty I built. I used engineered high pressure containment for the CO2 compressed to liquid and a pball regulator to consistently reduce pressure for the rest of the gun.

You can't really regulate pressure when putting CO2 into the mag. In order to get even shot consistancy and actually be able to fire off a full mag, the gas needs to be kept in a liquid state.

Your mag would never take it. KABOOM, or HISSS if you're lucky.

If you did manage to get it in there (not likely), regulation would have to come at the outlet valve.

Certain guns like the W.E. line do iit this way. It's the only way to get it to work.

Does the gas have to be stored in the mag as a liquid?
Could you not use a regulator to lets say administer 120 PSI to fill the mag?
Maybee im not seeing the whole picture here?

[ILLusion]

If you regulate it into the mag, you're essentially putting the gas into the mag in it's gaseous form.

You'll be lucky if you can get 3 shots off before running out of gas, with a drastic difference in velocity between the 3 shots.

Liquid form is how gasses are stored in the small confined spaces of gas airsoft guns in order to maintain a somewhat stable output level as well as getting more shots.
That's why you fill mags with duster/propane tanks upside down. To inject the liquid.

ok.. got ya... thanks for the clarification!

cyber gun or some thing like that made a co2 adapter not sure what brand of guns it works with. it comes with a new fill valve with a qd adapter on it you have to have the hose goin to the mag all the time though. heres a bad pic

The density of propane as a liquid is roughly 300x as dense as gas at equivalent density (weight/volume). The space in a mag is quite limited so you need to store propellant in a dense form. You also get constant pressure behavior (assuming you allow the mag to warm between shots) from shot to shot with a liquid phase. Straight gaseous phase would mean a decay in pressure with each shot according to your ideal gas laws (remember high school chem?) which don't apply in 2 phase systems (liquid present).
