19 Other Firearms Definitions You Need To Know


Collapsible Stock

Beavertail

A large piece of curved metal at the top of the grip on a pistol which protects the user's hand from getting "bitten" by the hammer or slide. It is nearly always the top part of the grip safety commonly found on many 1911-style pistols.

Biathlon

A shooting sport that combines both skiing and rifle shooting. It is the only shooting activity in the Winter Olympics. There is also a summer biathlon which involves running and shooting but it is not yet an Olympic event.

Muzzle Velocity

The speed of a projectile or a load of shot at the point that it exits the muzzle of a firearm, normally expressed feet per second.

Firing Pin

A needle like metal part of a modern firearm that gives a vigorous strike to the primer initiating the firing of the cartridge.

Down Range

The area of a gun range where firearms are pointed when they are fired. The area of the range forward of the firing line.

BATFE

Abbreviation for the Bureau of Alcohol, Tobacco, Firearms and Explosives

Front Sight

The front sight is placed at the muzzle end of the barrel. It is often (but not always) in the form of a dot or a blade. To attain a proper sight picture and shoot with the greatest degree of accuracy, the shooter's eye should be focused sharply upon the front sight while shooting, allowing both the rear sight and the target to blur somewhat.

Speedloader

A device used to reduce the time and/or effort needed to reload a firearm's magazine.

Bang Stick

A specialized firearm used underwater that is fired when in direct contact with the target.

Dummy Round

An inert ammunition-shaped object, used in practice to simulate misfeeds and other malfunctions and also used in dry fire practice. Unlike a blank, a dummy round contains no charge at all. A snap-cap is a type of dummy round.

Primer

A small metal cup that contains a tiny explosive charge that is sensitive to impact. A primer is placed in the base of a shell casing to ignite the powder of the completed cartridge. It is detonated by the striking of a firing pin in the firearm.

Short Recoil

A semi-automatic pistol in which the barrel and breechblock are locked together for only a short distance of rearward recoil travel, at which point the two are uncoupled, the barrel is stopped and the breechblock continues rearward, extracting the spent casing from the chamber. Upon returning forward, the breechblock chambers a fresh round and forces the barrel back into its forward position. Most modern recoil operated semi-automatic pistols use short recoil.

CQB

Abbreviation for Close Quarters Battle.

Fulminate Of Mercury

A highly sensitive explosive used as a primer compound.

Magazine Loader

A mechanical device to make it easier to fill magazines using less hand strength and without hurting one's fingertips or thumbs.

Model 70 Type Safety

A small lever mounted to the cocking piece of a Winchester Model 70 rifle, rotating on a vertical axis from front (Fire), halfway back (Safe, but allowing bolt movement), and fully back (Bolt and firing pin locked Safe). While, like the Mauser, commendable for locking the firing pin instead of just the trigger, its fore and aft movement is both easier to operate and it allows lower mounting of telescopic sights, reducing parallax between the line of sight and the line of the bore and increasing the range of distances for which the scope may be reliably sighted-in.

Cylindro Conoidal Bullet

A hollow base bullet, shaped so that, when fired, the bullet will expand and seal the bore. It was invented by Captain John Norton of the British 34th Regiment in 1832, after he examined the blow pipe arrows used by the natives in India and found that their base was formed of elastic locus pith, which by its expansion against the inner surface of the blow pipe prevented the escape of air past it.

Turk's Head

A tip for a cleaning rod, a jag, with spirally-radial wires for vigorously scrubbing a gun's bore.
