c02 pressures for GBB use
 

heys guys just wonders of anyone knows the psi equiv for CO2 in a standard GBB mag?

the particular gun in question at the moment is a TM hardkick Desert Eagle.

I know alot more oiling/cleaning maintance will be required running CO2 through the gun. but that's not the question .

I just need to know how much psi would be the equiv to Propane ... and if anyone knows how much psi the mags can take period that would be nice too.

eventually the gun will be completely upgraded internally and metal slide (hopefully frame too but not holding my breath) .. with pressure changes to vary from target shooting ... to occasional field play.

CO2 will destroy the gun.

If you want a CO2 desert eagle buy the CO2 KWC one.

800+ vs 160ish IIRC, enough to turn your pistol into a grenade

that's kinda what the regulated filler is for.... so I can only fill it to 160ish psi instead of a full load 800+... which is why I asked the pressure :P

The equivalent CO2 psi will yield less volume than propane, thus depleating your reservoir very quickly.

With stock TM mags, you'll blow the seals. Heck even with my upgraded and sealed mags it would blow. Forget the fact that the valves will fail faster.

When the gas in a container hits it's maximum pressure some of it will revert to liquid.

CO2 will not revert to liquid at any usable pressure, so it will work for a shot or two but nothing more.

The advantage of using gases like propane or CO2 is the ability to store vast amounts of extra gas in liquid form, else we would be using compressed air for consistency issues like in paintball.

The concentration is the key concept. Because a 3cm square container filled with CO2 at 160 psi is considerably less then a 3cm square container filled with propane at 160 psi.

It has to do with the molar concentrations of the gasses themselves and the properties that they exhibit at those concentrations. Lets just say that injecting 3 cubic centimeters at 160 psi of CO2 would probably rack your slide once if your lucky.

If you want a CO2 gun get a CO2 gun.

so how would HPA work regulated and in a gbb?

it wouldn't, at least not unless you run a hose into the bottom of the mag with a regulator running out of an HPA tank.

Because the HPA doesn't turn into a liquid?

Thanks guys. I was avoiding the chemistry lesson unless required.

OP, if propane GBB mags were capable if running CO2, don't you think we'd be all over that? Same deal with HPA as it is already compressed air and won't compress more into a liquid form to maximize space/volume

hey not trying to stir the pot.. all above makes sense, I just always saw alot of people say that c02 wasn't cost effective, and that max pressure wasn't safe (that I already knew)

propane basically makes me wanna puke (I've gotten a blast of propane in the face form a previous GBB during a game and threw up in my hiddy hole...) .. and I can't use it inside for testing, etc

guess I'll have to run on Green gas... anyone know of a specific brand of Green that isn't really heavy on the silly oil?

what you got against oil? O.o

since green gas is propane with a bit of fragrance....

use duster indoors if you have such an issue with propane.
