Empire has been making paintball CO2 bottles for many years.  (These were called “Pure Energy” bottles before).  The valve is standard for all paintball guns.  If your paintball gun uses a CO2 bottle, this tank will work for you.  We have found the Empire CO2 bottles to be some of the most reliable paintball bottles made.

• This tank will ship EMPTY.  You must have it filled at a sporting goods store, a paintball store, or a personal fill station before use.
• CO2 tanks to dot not need a gauge to tell how full they are.  The liquid CO2 is measured by weight, not pressure.  If you have a scale you can measure your 'empty weight' and compare that to the current weight of your tank to see how much CO2 is in it.
