Arsenal Exchange - Firearms Classifieds - Industry Directory

Hang Fire

An unexpected delay between the triggering of a firearm and the ignition of the propellant. This failure was common in firearm actions that relied on open primer pans, due to the poor or inconsistent quality of the powder. Modern weapons are susceptible, particularly if the ammunition has been stored in an environment outside of the design specifications. Reloaded ammunition may also be the cause if not reloaded properly

Bluing

Also spelled blueing. A passivation process in which steel is partially protected against rust, and is named after the blue-black appearance of the resulting protective finish. True gun bluing is an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite (Fe3O4), the black oxide of iron, which occupies the same volume as metallic iron. Bluing is most commonly used by gun manufacturers, gunsmiths and gun owners to improve the cosmetic appearance of, and provide a measure of corrosion resistance to, their firearms.

CCP

Abbreviation for Concealed Carry Permit.

Weapon

Anything that can be used in an offensive attack or in defense of an offensive attack. Guns are not necessarily weapons.
A gun can be used as a weapon, but so can a pencil, fist, car, a wad of paper or any other object used to attack or retaliate against an offensive attack. Even words can be used as a weapon.
Guns and other objects should be always called what they are; gun, rifle, pistol, pencil, knife, tomato or whatever they are. They should never be referred to as a weapon, EVER.
Some examples of the proper usage for the word "weapon" would be:
"One weapon used in the attack against the left flank was dirt clods".
"The marshmallow gun was the weapon of choice used in the accounting vs marketing skirmishes."
"The liberal leftists use words and restrictive controlling laws as weapons against the freedom of the people."

Furniture

Generally refers to the stock and fore-end of a rifle. Can sometimes also be applied to any detachable accessories like a flashlight.

Trajectory

The arc described by a projectile (or a load of shot) after it exits the muzzle of a firearm. Falling objects accelerate downwards at a rate of 32 feet per second, per second. The faster a projectile travels, the greater the distance it can cover in a given time before dropping too far. Hence, the higher the velocity of a bullet, the flatter the trajectory it will achieve.

Heel

The top of the butt-end of a gun stock.

Double Rifle

Two independent rifles, built on one frame, designed to allow two virtually instantaneously quick, totally reliable shots. The barrels may be arranged either side-by-side or over-and-under. The apogee of the gunmaker's art. Particularly useful against dangerous game, which may be moving, and in your direction, with vengeance on its mind.

COM

Abbreviation for Center Of Mass.

Chain Gun

A type of machine gun or autocannon that uses an external source of power to cycle the firearm.

Bang Stick

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

Feed Ramp

An inclined, polished area on a repeating firearm, just behind the chamber, that helps guide a cartridge into the chamber when pushed forward by the closing bolt or slide.

Brick

A box of ammunition roughly equal in size and weight to a brick. Most often used to describe a 500-round container of .22 Long Rifle ammunition.

Neck

The forward portion of a bottlenecked cartridge case. Also the portion of a rifle chamber in which the neck of the cartridge case rests.

Center Hold

A sight picture of when the center of the target is half covered by the front sight when the sights are properly aligned. Also see six o'clock hold and cover hold.

Range Finder

A device used to determine the range to a target. Many range finders work by bouncing a laser beam off the target or nearby object and measuring the time for the reflection to arrive back at the instrument. It is also possible to use various passive optical devices such as a mil-dot telescopic sight.

Gape

The degree to which the barrel(s) of a break-open gun drop down; the size of the opening space, which should be sufficient to allow for ease of loading, unloading and properly-functioning ejection. A good gape is easier to achieve on a side-by-side than an over & under where the bottom barrel is well-enclosed by the action body.
