CO2 question

[AzNGuNSmokE]

I need to try out a few modifications I did. My On/off was too long (way out of spec) and I need to trim it down to the correct length. All the stores around me are closed so I can't get an HPA fill. Is it ok if I Take 15-30 shots trying out various length using CO2.

This is on an E-mag and the CO2 tanks is anti-siphoned and held in the correct position and to make sure even less liquid goes through I will use a remote and a stab. (NOTE THE TANK IS NOT IN vertical position, so the remote will help reduce liquid with the Anti-siphon).

What is it that the retro-valve can't use co2. Is it because of the different density of CO2 and the way the valve uses heat? Or is it just liquid co2 getting in the valve? I can't see to much damage being done since these are controlled conditions and not playing conditions where the tank will be in various positions.

Thanks For your help.

DO NOT USE CO2 IN A RETRO VALVE!

The valve recharges so quickly that you'll get liquid CO2 in the valve and freeze every single oring you have. These orings weren't designed for the cold temp that CO2 gives.

No matter what modifications you have, you CANNOT use CO2 in a gun equipped with the ReTro valve. EVER.

CO2 in a retro valve will cause condensation no matter how you attempt to keep liquid out. Its the properties of the gas that you can't change and the fact that the retro valve recharges so fast through small ports controlled by o-rings. The condensation would cause freezing and high pressure CO2 gas would vent all over the place in an uncontrollabled fashion.
