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.
Which model? If it is the t9 or t8 pistol then you have to buy an adapter for a 20 oz tank.
Do you mean a Co2 tank, or a carbon fiber HPA tank. Either Way you simply screw in onto the back.
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 To be honest though CO2 is well out of date.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.
