| Term | Definition |
| 12g. | 12 gram CO2 "powerlets" used for many years in pellet rifles. Powered the early paintball guns. |
| APG | |
| A special bulk CO2 tank designed to prevent the gun from sucking liquid. | |
| Barrel Plug | A plug that goes in the business end of the marker's muzzle. It prevents projectiles from accidentally leaving the gun. |
| Bottom Line | Usually refers to the localation of the CO2 tank on the bottom rear portion of the marker's pistol grip.Desired since it makes siting the gun with a mask on much easier. |
| An object or embankment on the field that a player uses for cover. | |
| To charge a bunker and eliminate, a close range, any players hiding behind it. | |
| CA | Constant Air--allows marker to use bulk CO2 tanks rather than 12 gram. |
| A device used to measure the velocity (speed) of a paintball coming out of a barrel. The safe maximum speed of a paintball is 300 feet per second. | |
| CO2 | |
| Feeder | A larger "hopper" which holds paintball pellets, feeding them into the gun through its bottom. |
| An electronic device which is located at the base of the feeder. The agitator insures that balls feed through the bottom of the feeder and do not "clog" up. Often used on very smooth firing guns like the AutoMag or AutoCocker since these guns "shake" very little. Can also obsolete a Power Feeder since it insures that a pellet will always be available to the gun. |
|
| fps | Feet per second. The measurement of speed at which the paintball travels. 300 fps is the maximum velocity a paintball may travel safely. |
| Harness | Belt/harness system for carrying loaders of paint so that a player may reload their feeder/hopper on the field during play. |
| HPA or Compressed Air |
High pressure compressed air (3000 to 4500 psi) is usually used instead of CO2 in tournament paintball. The use of HPA requires specialized high pressure tanks and regulators which lower the output pressure to what the paintguns can handle. |
| IPPA | International Paintball Players Association Although this organization has disbanded. |
| PSI | PSI stands for Pounds Per Square Inch and is a measurement of pressure. |
| Remote | Hoses and fittings which allow the bulk CO2 tank to be detached from the manufacture's intended location on the gun, then located elsewhere (e.g. on the player's hip). |
| A special CO2 talk designed to suck liquid into the gun. | |
| Speedball | Speedball is a game played on small fields with little natural cover. Bunkers usually consist of wooden pallets, tires or other man-made barricades. Speedball fields are designed to allow spectators to see the action. |
