If you want to try and fix it yourself you will need to know where the leak is coming from, easiest way to find that is to get onto a paintball form and start asking questions. once you know where it is coming from you can replace the seal that has gone bad. If you dont want to work on it yourself the next best thing is to send it into a shop and have them work on it.
Check your gun's documentation and the bag of small parts that may have come with it. Many have a cup seal or similar mechanism and explain in the documentation how to inspect and/or replace it. Some even come with a spare seal.
Yes, the tanks have the same size fitting to connect them... Co2 is hard on the seals so may want to go through and replace them...
The hopper will, but it won't be able to fire them.
The first paintball guns were used to mark cattle. They resembled a pistol.
You must be 18 to purchase paintball equipment.
No it won't fire, Co2 is the power source that power the gun.
Your marker could be leaking from a small pinhole in your frame, or it could be leaking out of the CO2 adapter itself. you may want to have it checked, if it is a electric marker, you could freeze your circuit board.
Read the directions for YOUR gun. CO2 does not explode, but may leak down.
Co2 comes out of a bb gun because of the compressed co2 cartridges that are used to propel the bb itself. Additionally, the bb gun that does not use co2 cartridges just doesnt shoot out co2, but air in general.
Well no a Co2 cun justs uses compresed Co2 intead of a spring or a batery Co2 if fairly cheap and are easy to use
A paintball gun needs CO2 (or HPA) to fire at all.
No their about the same
All Co2 tanks will fit any gun meant to be powered by Co2.
