No paintball gun will work without a CO2 tank or other propellant tank. without Co2 there is nothing to push the ball out of the barrel.
No, any tank will work.
99.999% of the time yes, anything that will work on CO2 will work better on HPA
your question doesnt tell me what is going on, you screw in the tank to fill the marker with co2 but if that is not happening then your tank may be empty, if the marker will not fire I can not help you without further information but try cleaning it out and oiling it, a lot of times that will fix it
No, no paintball guns work on hydrogen.
It will "fire" but the ball will just roll out of the end of the barrel.
There are no cheats for paradise paintball.
If it has a special tank, like you couldent buy one at a local shop, then no. If it has standard ASA threads, you can hook up a coil to anything.
Yes, but certain markers will not work as well with it. It is a lot easier then getting HPA guns to run CO2.
Paintball stores usually wont hire anyone under the age of 18.
No, you should use only paintball specific of air tool lubricant.
