changing from compressed air to CO2

[modifiedspyderimagine04]

I'm just seeing if theres a way to change an RSX from running compressed air to CO2?

[bigred76]

Yeah, you have to get a carburetic converter and run a 3:1 spring ratio, and replace the valve, striker, and bolt with a specially designed cold weather model.























No, just screw in the CO2 tank and it'll run for a little while. Anti-siphoning your tank would be the only advisable semi-permanent route. It's just not the best gas to use for the marker, especially if you're already using HPA.

Is there any guns out there that are compatible with RSX to transplant parts to make it use CO2?

LOL... Bigred is screwing with you. All you have to do is screw in the Co2 tank & have fun.

Im wondering why you would want to convert back to Co2? Is it harder to get HPA or what?

[modifiedspyderimagine04]

Yeah its hard to get HPA around here. I had to drive 1-2 hours to fill up my tanks + the cost of gas for the car. I didnt know u could use CO2 on an RSX since it has a regulator on it.

The RSX has a vertical regulator. It's not a very good regulator, but it's good enough for it's purpose. Just hook up the CO2 tank, and look into ways to have a 20oz Anti-Siphoned to make it so the CO2 doesn't cause as much chuffing or odd issues at high ROF's.

Whats the difference between the regular and the Anti-Siphoned CO2?

[bigred76]

A/S (anti-siphoned) has a tube that gets the gas straight from the top of the tank. A CO2 tank without one gets whatever's in front of the valve. CO2 tanks are typically 60% liquid, so you're getting only 40% pre-expanded gas when you shoot. which leads to cold regulators, chemical burns from extreme low temps, chuffing, and a whole bunch of other issues.

[modifiedspyderimagine04]

Wouldnt an aftermarket expansion chamber help a little on the CO2 turning to a gas?

[bigred76]

Sure, but where are you going to put it? Piggy-backed on the regulator? No, that would not be a feasible solution. An Anti-Siphoned tank is easy enough to come by. Hit up the user "druid" on these forums with a PM, he might just do it for you so long as you provide the parts (CO2 tank and the money for the A/S kit), your ASA from the marker you'll be using it on (so it's arranged properly inside the tank), and some money for his time.
