A:
Action-The mechanism by which something is operated, as that of a gun;  A military encounter, as a battle or
    skirmish;  Actual combat with enemy forces.
Agitator-A device that is attached to a  paintball hopper or incorporated into the designof the hopper.  It has
    a shaft that enters the inner enclosure of the hopper with some type of impeller attached to the end of it.
    When activated the agitator  rotates the impeller which moves the paintball around inside of the  hopper
    allowing them to align with the feed port, located at the bottom of the hopper, and fall freely into the
    hopper feed nipple.
ASA-The abbreviation for Air Source Adapter;  Also referred to as: CA Adapter; A device that is designed to
    allow a constant air tank to screw into it and let the Co2 gas in the tank pass through it. In most cases the
    ASA Adapter is designed with a actuating pin. When used with a constant air tank that has a pin  valve, the
    ASA Adapter pin actuator presses in the pin valve's pin and allows the flow of Co2 gas from the tank into
    and through the ASA Adapter. The gas then goes to the paintguns valve mechanism either directly or
    indirectly via some type of gas line.
Auto Trigger-A trigger and sear design used with pump action paintguns, that allows the user of the paintgun
    to have the gun fire each time the pump handle is pulled back allowing gun mechanism to be cocked and
    then pulled full forward. The gun will fire automatically when pump handle is returned to full forward
    position each time the pump handle is cycled from front to rear and back as long as the trigger is being
    held down.
B:
Barrel Plug-A safety device that is inserted into the front end of a paintgun barrel to prevent a paintball from
    exiting the barrel.
Bolt-The internal part of a paintgun that is common to Stock, Pump Action and Semi Auto paintguns. The bolt
    usually has a O-ring(s) at the front end of it. The O-ring acts as a seal between the bolt and the inner wall of
    the paintgun barrel when the bolt is in the full forward position. The bolt performs two functions: 1. It is the
    device that moves the paintball from where it is loaded into the chamber of the paintgun, to the bore of the
    paintgun barrel. 2. It is the device by which Co2 gas is transferred from the paintgun valve system to the rear
    of the paintball via the front of the bolt.
Bolt (closed)-One of two design criteria by which semi auto paintguns are manufactured. The closed bolt
    design means that the bolt is in the full forward position with the bolt O-ring sealing against the inner wall of
    the paintgun barrel when gun is ready to be fired via the trigger. This is with respect to the paintgun being
    connected to a Co2 gas supply (constant air tank or remote air system) and fully pressurized.
Bolt (open)-One of two design criteria by which semi auto paintguns are manufactured. The open bolt design
    means that the bolt is in the full rear position with the bolt just behind the feed nipple port (the port that
    allows the paintballs to flow into the paintgun body) when paintgun is ready to be fired via the trigger. This is
    with respect to the paintgun being connected to a Co2 gas supply (constant air tank or remote air system)
    and fully pressurized.
Bottle-Slang for tank; The container part of a constant air tank.
Blow back-Paintball gun's leakage of Co2 gases between the bolt and the inner barrel wall and/or leakage of
    Co2 gases from the cocking mechanism between the gun's hammer and inner wall of the gun's housing.
    Blowback may occur for two reasons. First, and easiest to fix, is that the O-rings on the gun's bolt and/or
    hammer need to be replaced. The second reason for blowback is more complex. It has to do with the
    positioning of the gun's components at the time that the Co2 gas is released into the gun's barrel.
Bottom Line-A style of constant air system where the ASA adapter is located at the bottom of the paintball
    gun's grip frame. This ASA adapter is where the constant air tank is connected to the paintgun. The ASA
    adapter may be designed into the grip frame so as to be part of the grip frame or it may be a after market
    ASA adapter that is mounted to the bottom of the grip frame. If it is a after market ASA adapter it will have to
    have a gas line connecting it to the paintgun in order to allow gas to flow from the tank into and through the
    ASA adapter to the gas line and then to the paintgun.
Breech Lock System-A design that prevents the paintgun from being accidentally pumped twice before it is
    fired once. Breech locking guns MUST be fired before the gun can be pumped again.
Butt Plate-A device that fits on to the end of a tank allowing it to be used as a shoulder stock.
C:
Caliber-The diameter of the bore of a gun taken as a unit of measurement.
Carbon Dioxide-Also known as: Co2. A colorless, odorless, incombustible gas that has many purposes such
    as: dry ice, the carbonation in carbonated beverages, and in fire extinguishers. Co2 is present in the
    atmosphere and formed during respiration. Co2 is a compound gas made of oxygen and carbon. Co2 stores
    it's energy when it is in a liquid state and releases it into a usable force through expansion into a gas. Used in
    paintguns as a pressurized gas (power source) for shooting paintballs out of the paintgun's barrel. With
    respect to semi auto paintguns, Co2 is also used for recocking the paintgun.
Check Valve-Allows substance (such as gas, liquid or solids) to flow in only one direction. Once passed the
    check valve the substance cannot flow back through check valve.
Chronograph-Electronic device that measures the speed of an object directed across it.
Co2-The abbreviation for Carbon Dioxide.
Constant Air-the use of a refillable gas tank that is connected to a paintgun and supplies the Co2 gas
    necessary to power the operation of the gun. The term "Constant Air" was derived from the fact that the
    paintgun would have a prolonged supply of gas and would be able to get 300 to 1000 shots per tank of gas,
    depending on size of tank and type of gun. This was opposed to paintguns that used 12 gram Co2
    cartridges and only got 15 to 25 shots per cartridge on the average.
Cycle Rate-Indicates the number of cycles a paintgun can perform per second.
D:
Detent, Ball-Sometimes call: Ball stop, anti-doubler, wire nubbin. A device that keeps no more than one
    paintball from loading into the chamber of a paintgun when the paintgun is executing one cycle. It does this
    by maintaining the paintball in a stationary position until the paintguns bolt pushes the paintball into the barrel
    of the gun.
DIisk, Rupture-A small copper disk in the valve of a tank that is designed to rupture if the pressure in the tank
    becomes too great. The rupture disk is usually held in place by a safety plug that has vent holes in it.
Double Action-Requiring only one pull of the trigger to cock and fire.
Elbow-Connects the hopper to the feed port
Expansion Chamber-A device which conditions Co2 gas by allowing it to expand before it enters the
    paintgun's valve system.
F:
Feed Port-Also known as: Feed nipple. The feed nipple is a short tube that is connected to the paintgun
    housing at an angle of 45 degrees. It provides the passage by which paintballs move from the paintball
    hopper, through the hopper adapter, which attaches to the feed nipple, and into the chamber of the paintgun.
    Commonly, feed ports for pump action paintguns are one inch in diameter, while semi auto paintguns have
    seven eighths inch feed nipples.
Feed Plug-A plug at the bottom of a power feeder that angles the balls into the feed port. It can also be turned
    to stop the balls from feeding into your gun.
Feed Tube-A paintball storage container tubular in form; When playing Paintball the player uses the feed tube
    to reload his paintgun's hopper.
Feeder-Slang for hopper.
Fill Station-An apparatus consisting of at least one valve used for exhausting pressurized fill hose, a fill hose
    and some type of fill adapter for connecting a constant air tank to one end of the hose. It is used  for filling
    smaller constant air tanks with liquid Co2 from larger siphon fill tank. The large siphon fill tank is usually 50 to
    60 pounds in volume weight.
Flag Station-A team's base camp and is the location where a team's flag is kept. It is also the location where a
    team must return the opposing team's flag in order to win the game.
Flank-1. The extreme right or left side of an army or fleet. 2. To stand or be placed or posted at the flank or side
    of. 3. To defend or guard at the flank. 4. To menace or attack the flank of.
Fore Grip-A horizontal grip generally located on the front of a gun. This grip is generally grasped with the
    players off hand; i.e. the hand not on the trigger frame; to stabilize the gun for shooting.
F.P.S.-Abbreviation for 'feet per second'. This is the standard method in the U.S. for determining the speed at
    which a paintgun is shooting.
G:
Gas Efficiency-Refers to the amount of shots a gun gets in relation to the amount of liquid Co2 it uses.
Gogged-A player who has taken a hit square on his goggles
Goggles-Eye protection worn by players to prevent eye damage. Paintball goggles are specifically designed
    for the sport of paintball and should not be substituted with goggles made for any other application other than
    paintball.
Grips-Components that fit on the paintgun grip frame and provide surface area by which the shooter may grip
    the gun. Grips are replaceable on many types of paintguns. Different styles of grips can provide greater
    comfort and ease of use for the individual paintball player. Different styles of grips include rubber, wood,
    and wraparound types.
H:
Hammer-Also known as: The lower bolt or the striker. This component, when released from the cocked
    position, strikes the valve assembly and forces it open. When this striking of the valve assembly by the
    hammer occurs, Co2 is allowed to pass through the valve assembly from the gas source to the paintgun
    barrel.
Hammer Sear-The part of a gun that retains the hammer in a fixed position, usually under main spring
    pressure. When the trigger is pulled by the shooter's finger, it pushes against the sear allowing it to release
    the hammer and thus allowing the hammer to strike the valve assembly.
Harness-The combination of straps, pouches and other parts forming the working gear worn by a paintball
    player to carry paintball, Co2 cartridges, tanks, squeegee and anything else he/she requires to play the game
    of Paintball.
Hopper-A container used to hold paintballs, usually with a lid that covers the opening where the paintballs are
    loaded into it, and has a feed nipple at it's bottom.
I:

    relation to each other. An in-line configuration indicates that the bolt and hammer are in line with each other
    one behind the other.
Lenses, Thermal-A dual lens system. The outer lens is made of a super hard polycarbonate material. The inner
    lens is made of a different polycarbonate composition that allows anti fog jell coat to stick to it. The two
    lenses are attached to each other by means of a rubber gasket that makes a air tight seal between the two.
    The space between the two lenses is called a thermal barrier and helps to reduce fogging on the inner lens.
Loader-Slang for hopper
M:
Muzzle-The mouth, or end for discharge, of the barrel of a gun, pistol, etc.
Muzzle Break-1. A pattern of holes or slots machined into the end of a barrel that act as exhaust ports.  2. A

    guns have an in-line bolt and hammer system.
Nitrogen (N2)-Refers to Nitrogen gas. A colorless, odorless, relatively non-reactive gas which is compressed
    to high pressures. The difference between Nitrogen gas and Co2 is that Nitrogen is measured by pressure
    while Co2 is measured by weight.
O:
O-Ring-A ring of pliable material, as rubber or neoprene, used as a gasket.
Off Set Sight Rail-A sight rail that is mounted at an angle away from top dead center of paintgun body. The off
    set sight rail allows a sight to be mounted so that it is unobstructed by other parts of the paintgun.
P:
Paintball-A round capsule filled with brightly colored water based dye that is designed to break upon impact
    leaving a splat mark on the object it hits. Paintball sizes are: .50 Cal., .62 Cal. and .68 Cal., the last being the
    most current size and readily available. The .68 caliber paintball offers much better range, accuracy, and
    breakability due to its' size and mass.
Paintball Gun-A mechanical device, usually powered by Co2 gas, used to propel paintballs.
Paint Check-The suspension of play during a game at which time a player is checked for splat mark(s). A paint
    check may be called by referee or player, but may be only invoked by a referee and game may only be
    restarted by referee. Misuse of the paint check rule by a player is cause for that player to be removed from
    current game.
Powerfeed-A feed nipple design that incorporates the blowback from the paintball gun to increase the rate at
    which paintballs are fed into the paintgun. Most power feeds are designed into the paintguns, but there
    are some after market bolt on power feeds available for guns like the VM-68 series of paintgun and others.  Powerlet-An icon developed by the air gun industry for Co2 cartridge. In Paintball it refers to 12 gram Co2
    cartridge.
Pressure Regulator-Regulates the pressure of gas flowing through it. Some regulators are preset to p.s.i., and
    some are adjustable.
PSI-Abbreviation for pounds per square inch.
Pull Pin-A pin fastener which can be removed quickly to speed disassembly of a player's paintgun.
Q:
Quick Changer-A device that is either a part of the paintgun or a separate unit that connects to the gun, usually
    via the ASA adapter. It allows the rapid loading and unloading of a 12 gram Co2 cartridge.
Quick Disconnect-Usually made of stainless steel or brass, this unit is composed of two parts, a male fitting and
    a female coupler that connect together to form a air tight connection. In paintball the quick disconnect is
    used by the player to quickly disconnect the Co2 source, such as a remote system, from the paintgun.
R:
Receive-The main body of a paintgun where the bolt and hammer are usually housed. A gun's feed nipple is
    typically a part of your receiver.
Remote System-Also known as a "Remote" or "Remote Set-Up". The system usually consists of a constant air
    tank that is carried on the player's body, usually in a pouch or fanny pak, and a high pressure gas line with
    quick disconnect and all the fittings required to connect it to the paintgun.
S:
Sheridan Based-Refers to those guns that are based on or are similar to the original Sheridan family of guns. A
    Sheridan based gun is generally discernible by its stacked design. The hammer and valve system are in the
    lower section while the bolt is in the upper section.
Sight Rail-Allows the mounting of a sighting system to a paintgun.
Sight Rail, Raised-A sight rail that is raised up off the body of the gun. The purpose for this is to allow the
    shooter a better field of view.
Sight, Red Dot-A optical sighting device powered by a battery that produces a red dot reticle. Red dot sights
    do not project a dot on target.
Skirmish-1. A fight between small bodies of troops. 2. Any brisk conflict or encounter.
Skirmish Line-1. The invisible line between two opposing teams that have confronted each other. 2. A
    formation taken where by players are positioned beside each other in a line.
Splatter-The residue sprayed on a player by a paintball when it makes impact with a object close to that player.
Spring, Main-The spring that drives the hammer.
Spring Valve-The spring that closes the valve after it has been opened by the hammer.
Squeegee-A device used to clean the barrel of a paintgun.
Stacked Configuration-Refers to the manner in which the bolt and hammer are positioned in relation to each
    other inside the paintgun receiver. A stacked configuration indicates that the bolt and hammer are stacked
    one on top of the other.
Supressor-A tubular device that is press fitted onto the front end of a paintgun barrel designed to reduce the
    amount of sound that is made by the gun when it is fired. Also known as Silencer.
T:
Tank, Constatn Air-A container or structure for holding a liquid or gas. In Paintball a tank is made up from two
    components, a valve and a bottle.
Tank, Anti-Siphon-A tank designed to allow only vaporous Co2 gas to exit the tank through the tank valve.
Tank, Siphon-A tank specifically designed to draw liquid Co2 from the bottom of the tank. This is
    accomplished by a gas line that is attached to rear end of the tank valve and weighting down the other end of
    the gas line  o that it remains located in the bottom area of the tank.
Thread Saver-Also know as: Bottle cap. A protective cap that screws onto a tank valve. This keeps the valve
    from being damaged while not in use.
Tool, Velocity Adjusting-Also called: Adjusting tool. A tool used specifically for adjusting the velocity of a
    paintgun.
Tournament Cap-A cap which covers a gun's velocity adjuster so that the velocity cannot be adjusted during
    game play, Normally required for tournament play.
Trigger Shoe-After market product that fits on the trigger of a gun to provide the trigger finger with more surface
    area to grip the trigger and comfortable feeling.
Twelve Gram-Slang for 12 gram Co2 cartridge.
V:
Velocity Adjuster-A component of a paintgun (usually a set screw) that when turned in either clockwise or
    counter clockwise direction will increase or decrease the paintguns muzzle velocity.
Valve-Any- device for halting or controlling the flow of something, such as a gas or liquid, through a pipe, out of a
    bottle neck, or other passage.
