The popularity of paintball as a combative game has grown steadily over the years. The object of the game is simple; two teams battle one another until one team is eliminated by the other. This is accomplished by the opponents shooting one another with paint pellets. While being skilled and in good physical condition is important to winning, using the proper equipment also plays a key role.

When looking for the right paintball marker, or gun, the type of propellant you choose is very important. It could mean the difference between winning and losing, especially for professional players who often play in very long games. Compressed air propellants are the most popular, while CO2 is also widely used.
