A paintball Hopper is a device which feeds paintballs into a paintball gun’s breech.  A Gravity Feed Hopper uses gravity which naturally drops paintballs into the paintball gun.  An Electronic or Motorized paintball hopper uses a motor to physically push or pull paintballs into the gun.  A paintball hopper in the olden days was also called a “loader” becuase it loaded the paintballs into the paintball gun.

A Paintball Tube is a plastic cylinder shaped container which holds 100, 140, or 160 paintballs.  Its designed to fit into a paintball harness.  A paintball tube allows for easy and safe transport of extra paintballs on to a paintball field during play. A paintball tube is also called a “guppy” or “pod”.

Carbon Dioxide is used as a propellant in paintball.  A paintball Co2 Cylinder (tank) is filled with a certain amount of Liquid Co2 (measured in Ounces).  The liquid CO2 expands into gas state which is what a paintball gun uses to project paintballs.  When a paintball gun is fired, a small amount of CO2 is released which pushes the paintball out of the muzzle of the paintball gun.

Liquid CO2 can cause a lot of problems if it enters into the gun, including sporadic pressure variations.
