converting an RT Mag for CO2

[athomas]

I beg to differ, there's no need to double reg the valve. While it would absolutely guarantee no over pressuring, the risk of shoot down imho, is too high. If he were to go that route, he could have it set high enough to use a level X without issue

If you're going to use CO2 on a retro mag you need to do this or you risk condensation in the passage ways of the retro valve. Condensation when it turns back into gas, will cause big pressure spikes and could also freeze the orings causing massive leaking. Giving up some performance is better than giving up the game.

For the price of a Stab you can buy a used classic valve :)

A classic valve would definately be the best way to go.

everyone keeps saying get a classic valve... they won't go into a normal RT body... the valve mounts into the body & uses a banjo fitting to get the air from the rail to the valve

try extending the line from the asa to the valve... i have seen some local automag nuts wrap up to 10' of macro in a coil on the side of there gun to give the co2 enough time ti expand... not sure if it works but give it a try.... hope this helps!

Longer hoses and such only prevent liquid from going into the valve. Its the rate at which the CO2 goes through the small passages in the retro valve that causes the problem. Thats why a lower input pressure works better. It reduces the rate at which the CO2 passes through the valve.

Adding another reg to a mag will not induce shootdown. I have seen too many people post that, and it just isnt true. One caveat though, it must be properly setup. Now if you use a Stabilizer set to 550-600psi as was suggested, you will help keep liquid out of the valve, as Co2 cannot stay liquid below that in most playing temps. Co2 can be used if done properly, is it ideal? No. But can it be done, yes, with proper set-up. If your playing outlaw, and cannot easily get HPA, go for it. I would recommend using a remote line and put the tank in a harness. Then do not rail on the trigger for long periods, 3 round bursts with a a pause between them will reduce the problems that may occur. If you can find an older Max-flow remote reg setup that will work very well. Again set it for 600 psi and go to it. If you have lvlx you should change back out to a lvl7 bolt. If you have your heartn on using a tank on gun, here is how I would do it. Get a 20oz tank, and a bottomline Palmer stabilizer. Set up the tank with an anti-siphon tube matched to the bottomline reg, in the configuration that your mounting it in. Then set the stab to 575psi or so. Have the person filling your Co2 tank, fill it 3/4 full, that will help keep a good sized area for the liquid Co2 to convert into gas. Then moderate your shooting. If you can find the older bottomline mount Maxflow that a tank would screw into, would work as well, as the stabilizer, but you have to make sure you get a high pressure spring, as most were set up for under 350psi operation.
