ACCESSORY RAIL: A metal track intended for mounting hand stops or slings.

ACCURACY: The ability of an airgun to consistently group a serious of shots within a diameter as small as possible, at a given distance under optimal conditions. Accuracy does not take into account human error or environment conditions such as wind and elevation.

AIR RIFLE: An airgun (also air rifle or air pistol) is a rifle or pistol that fires a projectile by means of compressed air or other gases. Most airguns use metallic projectiles as ammunition.

AIR RIFLE SCOPE: Designed as a rifle scope but sturdy enough for double recoil of a spring piston air rifle and normally for parallax within 10 yards.

AIRGUN: An airgun is a type of gun that uses compressed air or gas to propel projectiles, such as pellets or BBs, instead of traditional gunpowder.

BALLISTIC COEFFICIENT: A measure of how a projectile decelerates during its flight through the air due to drag. It is an important and useful concept that is used for ballistics calculations. The higher the BC, the more aerodynamic the pellet will be, and the smaller the BC of a pellet, the greater its air resistance.

CALIBER: The numerical value of an approximation of a pellet diameter, measured in inches or millimeters.

DEFLECTION: The change in the path of a projectile due to passing through a medium or can also can be caused by wind.

ENERGY: Kinetic energy of a projectile. Measured n Foot/Pounds or Joules.

FEET PER SECOND (FPS): Unit of measurement of the speed a projectile flies. Also see Meters Per Second and Velocity.

GROOVES: Grooves and Land make the rifling of a barrel. The grooves are the lowered areas between two lands.
