Back Bottle n A type of gun configuration where the source tank is attached to the rear of the gun body and acts as a stock for shouldering the gun.
Backspin n The reverse rotation of a paintball launched by special means, which in theory gives the ball lift.
Ball n A paintball
Barrel n the extension of the gun which gives it the ability to have a straighter approach at the target.
Barrel Plug n A safety device used to protect balls from escaping when an accidental discharge has occured.
Blow-back 1. n A type of paintball gun operating system where the opening of the valve releases gas in two directions, one to propel the ball, and the other to blow the linked bolt and hammer back into a cocked position. Two-tube blow-back page.
Blow-back 2. n Excessive gas traveling up the feed tube of the gun which can impede the smooth feeding of balls during rapid firing.
Blow-Forward n A type of paintball gun operating system in which gas released from the valve blows the bolt forward. The bolt pushes the ball into the bore and then the gas is released into the bore to propel the ball.
Bolt n A cylindrical internal component of a paintball gun which serves to push the paintball from the breech into the bore, and channel a burst of gas released from the valve to impact the ball and propel it.
Bolt v The act of fleeing the scene in a rapid manner. He just bolted, lets move up!
Bore n The inside of the barrel.
Bottomline n Device that allows a gas source tank to be relocated beneath the grip frame, originally designed for the purpose of allowing face mask clearance behind guns which had a back bottle set-up.
B.P.S n Balls Per Second. A unit of measurement concerning ROF.
Break n Refers to having a paintball break inside the gun. I didn't have any breaks.
Breech n The internal area of the gun into which the balls enter before being pushed into the bore by the bolt.
Breech v To infiltrate a fortification
Bunker n An object, usually man made, which is used for cover on a paintball field.
Bunker v To sneak up on someone, trap them, and shoot them at point blank range while they are behind a bunker.
Burst Mode n see Multi-shot mode
CA 1. n Constant Air. Any kind of bulk gas source, whether Co2 or HPA, but not a 12 gram cartridge. 2. n Compressed Air.
Cannon n A device used to fire multiple paintballs in one shot for the purpose of emulating artillery fire, rocket launchers, or grenade launchers.
Chamber n The area of the gun where the ball is loaded and is bolted out of the barrel.
Chronograph n A device which uses light sensors or radar to check the velocity of paintballs. Also see F.P.S.
Chrono v slang for the act of using a Chronograph.
Chop v the act of inadvertently chopping a paintball inside of the gun, usually by the bolt.
Closed-bolt n A type of cocking system in which the bolt is in a closed position (the bolt is in its forwardmost position and there is a ball in the bore) before the trigger is pulled.
Co2 n Carbon Dioxide. An inert compressed gas (stored in liquid form, but expands into gas) used to power paintball guns.
Cock v On most mechanical paintball guns, refers to the compressing of the main spring, and placing other components in a position where the gun is ready to fire.
Cocker n Slang term usually used to refer to the Worr Game Products Autococker, or one of it's clones
Cosmetic Enhancements n Additions made to a paintball gun or accessories purely for looks.
Cup Seal n A component usually attached to a valve pin or valve tube, which forms a seal on the valve of the paintball gun, holding gas in the valve chamber until time for release.
Cycle n refers to the complete movment sequence of the internal action of the gun necessary to fire one paintball.
Dead Man's Walk n A tactic used with the intention of making opponent believe a you are already eliminated from the game, when in fact you are not. Considered cheating under some field rules.
Detent n device which protrudes into the breech of a paintball gun, designed to keep the gun from feeding more than one ball during each cycle of the action.
Direct Feed n The feed tube attached to a paintball gun, setting the ammo hopper at an angle allowing it to use gravity to feed balls. Standard direct feeds place the hopper at a 45 degree angle from the bore of the gun.
Double Action n an operating system in which the trigger pull both cocks the action of the gun and fires the gun.
Double Trigger n a modified trigger where a person is able to use two fingers on the trigger instead of one, which adds an added BPS.
Drop Forward n A piece which attaches to the bottom of the paintball gun allowing the gas source to be relocated forward of its original position in order to make the gun more compact.
Dry Firing v firing your paintball gun without paintballs in it
Elbow n A short piece of tubing which makes a 45 degree turn and acts as a connector between the hopper and feed tube on paintball guns.
Electro n Any gun using electronics to control the action. Also see electro-pneumatic below.
Electro-pneumatic n Paintball guns which use electronically controlled solenoids to activate the pneumatic operation.
