This is an aluminum 20oz paintball co2 tank. The difference between our CO2 tanks is pretty basic. The larger tanks can hold more co2, which will give you more shots per fill.
NOTE: These tanks come from various manufacturers so the tank you receive will be from one of our top manufacturers. We do not put the manufacturer logo in the picture.Our tanks ship empty.
These can be re-filled at sporting good stores, paintball fields, and many other places.
