19 Other Firearms Definitions You Need To Know


Bedding

That part of the stock on a rifle or shotgun into which the barrel fits.

Bolt Face

The forward end of the bolt which supports the base of the cartridge and contains the firing pin.

Blowback

A semi-automatic firearm whose breechblock and barrel are not mechanically locked together when fired. In such case the breechblock immediately begins to separate from the barrel upon firing. Blowback is used in comparatively low powered weapons, in which inertia of the breechblock, and cartridge wall adhesion against the chamber, are sufficient enough to retard opening until breech gas pressures have fallen to a safe level.

Rifle

A shoulder-fired long gun which has a rifled barrel.

Shotgun Shell

The cartridge for a shotgun. It is also called a "shell," and its body is usually made of plastic (metal shotgun shells are very rare, paper shotgun shells are extinct) with a metal head. Small shotshells are also made for rifles and handguns and are often used for vermin control.

Twilight Sight

A rifle front sight with a extra-large, folding bead. Typically, in addition to the normal fine bead (which allows for more precision) the larger bead, while at a cost of potential accuracy, is more readily acquired in marginal light. Also called a Gloaming sight

Patch Box

Covered compartment in the buttstock of a rifle used to carry patches or other small items.

OFF

Oregon Firearms Federation. OFF is a Pro-Gun rights group based in Oregon and was founded in 1998.

Break Action

A firearm whose barrels are hinged, and rotate perpendicular to the bore axis to expose the breech and allow loading and unloading of ammunition.

Gas Vent

A passage built into a firearm to allow the safe conduct of unexpected gas, as from a pierced primer, to minimize damage both to the gun and to the shooter.

Hinge Pin

A short cylindrical rod of hardened steel running laterally near the front of the bar of a break-open gun's action around which the barrel hook revolves when the gun is opened. Over the decades, this pin and its complimentary hook can wear and a gun can sometimes "shoot loose" or "come off the face." The proper cure for this condition is to replace the hinge pin with a new one, slightly oversized, to compensate for wear on both itself and on the barrel hook.

Jump

The amount of change in the bore axis, measured both vertically and horizontally, while the projectile moves from the chamber to the muzzle when it is fired.

Hornady Magnum Rimfire

A type rimfire rifle cartridge developed by the ammunition company Hornady. .17 Hornady Magnum Rimfire (4.527mmR), commonly known as the .17 HMR, was developed in 2002. It descended from the .22 Magnum by necking down the .22 Magnum case to take a .17 caliber (4.5 mm) bullet.

Practical Shooting

A shooting sport that simulates the use of a small arm in its intended role either as a tool for hunting or personal defense. True practical shooting limits the small arms, ammunition, and accessories used to those items that would actually be used in the role simulated.

Bersa

A firearms manufacturer located in the city of Ramos Mejia in Argentina. The company was founded in the mid-1950s by Italian immigrants Benso Bonadimani, Ercole Montini and Savino Caselli, all of them mechanical engineers with experience working for Beretta. Bersa is most famous for their Bersa Thunder .380 pistols and the Thunder Ultra Compact Pro Pistols (available in 9mm, .40 S&W and .45 acp). The full size Thunder combat (Thunder 9) pistol is the standard sidearm of the Argentina Armed Forces, Buenos Aires Provincial Police and several other law enforcement agencies in South America. The company is well known among firearm enthusiasts for producing high quality guns at reasonable prices and it spends little money on advertisement. Lifetime warranty coverage is provided to the original owners. They are strong and well built, nicely engineered, accurate, visually appealing and very reliable.

Pistol Whip

To hit someone with the grip of a pistol.

Clearing

Unloading a gun and double checking that it is unloaded or fixing a malfunction so that the gun is ready to fire again.
