Most likely the O-ring is broken on your tank valve. It is a small circular yellow-clear ring at the top that seals the valve into the Air source adapter. just take the old one off and put on a new one.
most likely a valve oring in damaged.
you screw the adapter into the gun, and then the co2 cartridge.
All guns leak a little bit when you put Co2 in the gun. its normal
without CO2 or paintballs, you just put the bolt forward. In most guns this is how you de-cock after a day of play, but if you have a regulator, it may store a single shot. If you fire without co2, the gun will not cycle or fire a paintball, it will only go into the barrel. If you fire with no paintballs and co2, you may damage your gun.
an o ring is a rubber ring that is put around the valve co2 cylinder tank to secure the gas when it is inserted
Burning fossil fuels, like wood, coal, petrol, gas. The "C" attracts 2-Oxygen and forms CO2.
Do you mean a Co2 tank, or a carbon fiber HPA tank. Either Way you simply screw in onto the back.
Which model? If it is the t9 or t8 pistol then you have to buy an adapter for a 20 oz tank.
Take it to a shop! if you want to do it yourself the normal way is to put the bottle on scales and fill it from a larger bottle to a fill weight. To be honest though CO2 is well out of date. A smart move would be to move onto compressed air.
You can use co2 tanks if they are the anti-syphon tanks or if you put that on your tank put even then they are not recommended.
if u mean the tank that you put your shoulder against and what powers it. no u can get co2 or compressed air (compressed air is better for your gun)
There is no reason to put a paintball gun in a refrigerator, or any appliance for that mater.
