CO2 and Gas Blowback?
 

I want to know what is the big difference between the two.

C02 is a gas.
Gas blowback is a system that gas blowback pistols use to cycle and propel a BB.

We don't use CO2 to power our GBB's.

We use "Green Gas" AKA Propane or Duster Gas (Difluoroethane).

CO2 will damage your gun unless it was designed to be used with CO2 (CO2 is kept at a much higher pressure than what most GBB's are designed to be used under).

Although there are GBBs that take CO2.

Ok thanks for the answer

This may be a silly question but, are C02 pistols able to work in the cold? and will ten 12 gram C02 cartridges last me longer than 1 can of green gas?

The correct duster gas for airsoft use is HFC134A, which is tetrafluroethane. Difluoroethane is corrosive to rubber and will ear your seals. Also, it has lower pressure and will provide noticeably lower velocities than 134A.

It's not recommended to use duster gas you can get in most stores in your gun. If you have to use duster, then there are a lot of places online (mostly industrial supply places) that have 134A gas available.

And just as a side-note, the reason all store-bought duster gas is now difluoroethane is that kids used to buy the 134A gas and huff it to get high. You can't get high with difluoroethane.


CO2 works better in cold because of its high pressure. It will generally work where green gas guns will fail.

1 $3 can of propane will last you about the same amount of time as 10 CO2 powerlets (about $15 I think). You do that math for which is a better deal.

I use about 1 can of propane a year (I run a pistol every game and it actually sees use every game)

I've seen people go through 4 powerlets in a single game... Propane wins IMO.

I'd only use CO2 Powerlets for cold weather games for a GBB rifle.

Not a TF11 or any of those.

Otherwise propane for teh win.

Unless you dig having a hose running outta your gun than HPA wins :D
