Minimag problem

[shadowmaker]

I played all day until I switched from nitrogen to C02. when i switched to C02, air started shooting out the barrel and it was forcing balls out the barrel. This was a full 20 oz tank. It did this last time I played as well, only on the C02. Time for a parts kit? I m trying to get off of C02 all together but at the moment, I only have one tank for nitrogen and no way to re-fill it. First time the mag has let me down, missed out on 2 easy kills and had to call myself out.

Its a classic level 7 valve, completely stock. I think i bought it in like 94-95?? I see another post about the same problem but why doesnt it do it on nitrogen?

Your CO2 is freezing your o-rings making them brittle, preventing them from sealing. Keep liquid CO2 from entering your system (Anti-siphon, remote, expansion chamber, Stabilizer Regulator, etc.) and you should be "OK" on CO2 depending upon the ambient temperature at which you play.

However, HPA is EASILY ten times better than any CO2 system out there.

I m running an expansion chamber. I ve never replaced an oring in the valve. I think maybe Ive gotten my moneys worth.

And I agree HPA is better, just no way at the moment to refill in the woods.

Ive never had real good luck shooting mags on CO2 even here in florida, the difference between HPA and CO2 is like night and day.

When you put the CO2 tank on, make sure it is tilted away from the liquid source. Ie, the gun should be pointed up. If the bottle is anti-siphon, make sure it is properly setup for your gun or it will pour liquid into the ASA. Even an expansion chamber won't be able to handle it.

switching from Co2

I had this problem before with my tipmann. Never go from nitrogen to CO2, do the reverse and you should have no problems. nitrogen is warm air being shot threw your marker, when you put CO2 in the gun right after your shocking the Orings with freezing gases. Just play first with the Co2 then switch to nitrogen when it runs out and you should be just fine

The gas stage of CO2 is the same as the gas stage of air. CO2 won't freeze orings. Liquid getting into the internals can create an overpressure situation when it vaporizes. The freezing that most associate with CO2 comes from the rapid cooling and condensing of the CO2 gas which sucks the heat out of the surrounding areas. This can have a temporary detrimental effect on your orings, but usually only affects the rate of charge due to the air passages becoming smaller due to frost taking up space. Air has a lower temperature at which it condenses so you won't experience it using air in your marker.
