What does a CO2 regulator do?

[Tijn_416cs]

Hello there, first post, be gentle:3.
I'm making an airsoft M16 gun (will post pics when done), using some brass tubing, an air compressor pistol and an HPA/CO2 source. I really want to make the gun skirmishable, and carrying an air compressor arround isn't very handy I suppose. I heard about using regulated CO2 instead of HPA, and I know how you can make a CO2 gun. However, I have absolutely no idea what a CO2 regulator does. I want to get arround 20-30 shots per 12g or 16 gram cartridge, is this do-able?
Thanks, and have fun.

Co2 at room temperature has a vapor pressure of roughly 850psi. If you pulled straight off the co2 bottle...this is the pressure you would get.

If you run the co2 through a regulator, you can reduce the pressure to what ever the regulator set point is.

A good co2 regulator is the Palmers Pursuit female stabilizer...it will thread right onto a paintball style co2 cylinder and is adjustable for output pressure.

This one for low pressure...

The price of a Palmers plus c02 setup cost almost as much as a co2 airsoft gun tho... If you're looking into 20-30 rounds per cartridge (same as an airsoft co2 magazine).

Said it was good...never said it was cheap.

Different stage of life...tired of fighting with cheap sh1t and can afford good quality stuff...so I spend the money and don't regret it.

Never tried a Palmers, CP inline regulators are good enough for me while offer much bigger pressure range, not cheap neither tho.
