Hot shots are a reality using CO2 even with an expansion chamber. They result if liquid gets in close proximity to the valve and it is fired. Some of the liquid gets though the valve and then expands causing a higher velcity. And the dudes that walk around with their marker pointing down (like everyone) lets the liquid Co2 run right down into their gun. It is always the first shot. After the liquid is discharged the velocity turns to normal in a fire fight.

A regulator determines the output operating pressure between the regulator and valve. When liquid CO2 enters the reg and passes through it it instantly vaporizes from the drop in PRESSURE.

Just like at the fill station when they empty the tank.

You won't get any liquid PAST your regulator EXCEPT in the following scenerio.

When CO2 evaporates out of your supply tank it takes energy. That is why the bottle gets cold. When the supply tank temperature gets too cold the pressure in the tank drops with it. In a firefight, it can easily drop below the pressure your regulator is set at. In THAT situation, the regulator is wide open and some liquid could pass through. But it is during a firefight and unlikely except when it is over and you are walking around and looking for that next guy and holding your marker pointing down. Once past the regulator, it will eventually warm up and evaporate and have considerable excess pressure Behind the valve...

You don't need an expansion chamber AND a regulator. Both are large cavites that have thin walls and considerable surface area to exhange heat with a hot little hand.... You don't have a third hand, so why??????

Now I like a remote set up. Two advantages on disadvantage. It is a large coiled hose with lots of surface area relative to the volume. An ideal heat exhanger to warm up liquid CO2 and boil it into a gas before it reaches your marker.

It take a LOT of weight off your marker. Quicker to point and shoot. You can run faster holding it in one hand. After two days and a night of play at a scenerio game, you will appreciate NOT lugging all that weight around.

The disadvantage is you have to fight the hose if you are going to shoot off to your non dominate side. Two things happen if you aren't careful. Since it feels awkward, you tend NOT to take those shots. Since you don't take those shots, you tend NOT to LOOK out the left side. That makes you vunerable to guys like me that see a guy with a remote and look to see if he has developed that bad habit of not defending his non dominate side.

Now if you haven't yet bought a regulator, consider NOT getting one. If the reason you are buying the regulator is to solve your CO2 problems, be advised that a regulator will only make it better and will NEVER FIX all of your CO2 problems.

THE ONLY CURE FOR CO2 PROBLEMS IS THE GET A NITROGEN SET UP.

You can get a nice 48 ci x 3000 psi steel Nitro tank for the same price as a Palmers Stabilizer.

If you just have to get a regulator or want to go to LP and are CHEAP, send me an e mail and I will tell you how to get a used reg for $20-$30.
