The Definition of Airgun (Air Gun)
Airgun (Air Gun)
A variety of pneumatic gun that propels projectiles by means of compressed air or other gas, in contrast to firearms, which use a propellant charge.
Both the rifle and pistol forms (air rifle and air pistol) typically propel metallic projectiles, either pellets, or BBs. Certain types of air guns, usually rifles, may also propel arrows.

A game of competitive clay pigeon shooting on a formally designed layout. In plan view, one launching machine is located 16 yards in front of a straight line,
firing rising targets perpendicular to and away from that line. Five competitors shoot five individual targets at each of five stations along that line.
Although each target is presented at slightly randomized vectors, trap emphasizes generally a single type of shot, outgoing and rising,
and targets are broken at generally longer ranges than Skeet.
A safety which the shooter must deliberately disengage in order to fire the gun. The most common form of safety mechanism is a
switch that, when set to the "safe" position, prevents a pull of the trigger from firing the firearm.
A firearm loaded through the breech.
The person who supervises stores and distributes supplies and provisions.
Slang for a full metal jacket bullet with a round nose.
The term is most commonly used in referring to .45 ACP caliber ammunition, but may be used for other calibers as well.
A needle like metal part of a modern firearm that gives a vigorous strike to the primer initiating the firing of the cartridge.
Is a failure of the next round to completely enter the chamber. Misfeeds and failures to feed are very similar, a
failure to feed is a round that never even leaves the top of the magazine, while a misfeed is a
round that leaves the magazine but does not enter the chamber.
A type of firearm capable of discharging multiple individual shots in sequence, fed from a magazine, via the operation a lever, bolt, slide or some other form of manual operation.
A regular pattern of fine grooves cut into
the surface of a stock to aid in gripping a gun. Originally done for utility only,
checkering has become an art form in itself; craftsmen adorning the borders with ribbons,
fleur-de-lys, floral carving, etc. The amount of coverage, the precise regularity, and the
number of lines per inch indicate the quality of the work. Too-fine checkering, however,
defeats the purpose of the work altogether.
A premature, unintended discharge of a firearm that occurs as a round is being loaded into the chamber.
The distance, or clearance, between the base of a chambered cartridge and the breech face (or bolt face) of a firearm.
This is a critical dimension, particularly in high powered rifles. If there is too little headspace, the bolt will not close.
If there is too much headspace the cartridge will not be properly supported in the chamber and the cartridge will expand upon
firing and may rupture, blasting high-pressure gas into the action and possibly into the body of the shooter.
Headspace should be .003" - .006" in a centerfire rifle. It can be checked with a set of "Go and No-Go"
gauges specific to the calibre in question. (See below.) With a standard cartridge, the headspace is
registered by the shoulder, with a belted cartridge, the headspace is registered by the forward edge of the belt.
Any exercise in which a realistic scenario for the use of specific equipment is simulated.
In the popular lexicon this is applied primarily to tests of weapons or weapon systems that are associated with
the various branches of a nation's armed forces, although the term can be applied to the civilian arena as well.
Slang term for a firearm sound suppressor.
A firearm whose barrels are hinged, and rotate perpendicular to the bore axis to expose the breech and allow loading and unloading of ammunition.
A higher quality item used to increase accuracy, generally used for competition in a match. Match grade ammo and barrels are the most common improvements made to a firearm to improve accuracy for competition.
A concave, semi-cylindrical surface cut into the forward lump of a barrel set of a break-open firearm which revolves about the hinge-pin when the gun is opened.
A line, either imaginary or marked, from which people shoot their firearms down range.
A type of mechanism for removing a spent shell casing from the chamber of a firearm and inserting a fresh cartridge into the chamber.
This type of mechanism is most commonly used in shotguns and rimfire rifles.
