Cockers and CO2

I am thinking about getting an autococker and run it on CO2. What do I need (x-chamber, anti-siphon, just plug in and play)?

It depends on what kind of autococker. Older cockers were designed to run on unregulated CO2, while newer cockers are designed to be low pressure and reduce the pressure with an inline regulator.

In both cases, though, you are going to want to use anti-siponed CO2, because if liquid CO2 gets into your three-way valve, bad things will happen.

I've run many different 'Cockers on CO2, but only in warmer weather. At cooler temps (under 50-60 degrees), you'll have a hard time sucking enough pressure out of CO2 to keep it running. My rule of thumb is if it's warm enough to play in short sleeves, I'll use CO2; any cooler and I'll grab for the HPA tank.

Also, regardless of how old or new, a regulator will help any Autococker to be more consistent. An anti-siphon tube in the tank or using a remote line will help as well. Expansion chambers aren't really going to help much (if at all).

If you're running an older mid 90's cocker that was meant to run on direct CO2 I think you'd be OK using a bottom line to an expansion chamber. Not just a feed through but a proper multichamber expansion chamber. I'd still not want to go with it for really cold temperatures but down to maybe 50F I'd think it would be fine.

And running a larger 16 or 20 oz tank will give you more surface area for the CO2 inside to recover sooner by allowing more of the outside temperature to feed through the sides into the CO2 inside.

And I'd run an antisyphon with all this just as an added level of gas only security.

Regulators? PHTTHH! We don' neeed no steeeenkin' REGULATORS!....
