19 Other Firearms Definitions You Need To Know


Breech Pressure

The amount of rearward force exerted by the propellant gases on the bolt or breech of a firearm action or breech when a projectile is fired. The applied force has both magnitude and direction, making it a vector quantity. This is also known as Bolt Thrust on firearms that are Bolt Action

Group

A set of holes in a target left by a succession of bullets fired from the same rifle or handgun, using the same ammunition and sight setting. Fired (within the limits of one's marksmanship ability) to determine the inherent accuracy of the rifle/ammunition combination, and to aid in the proper adjustment of the sights.

Magazine Pouch

Commonly shortened to mag pouch, this is a device to hold extra magazines which fastens to the shooter's belt.

Receiver Ring

The portion of the receiver which is threaded so the barrel can be attached to it.

Long Recoil

A semi-automatic pistol in which the barrel and breechblock are locked together for the full distance of rearward recoil travel, after which the barrel returns forward, while the breechblock is held back. After the barrel has fully returned, the breechblock is released to fly forward, chambering a fresh round in the process.

Musket

A Muzzleloading long gun which has a completely smooth bore and is intended to fire a single projectile rather than a collection of shot.

Reflector Sight

A generally non-magnifying optical device that has an optically collimated reticle, allowing the user to look through a partially reflecting glass element and see a parallax free cross hair or other projected aiming point superimposed on the field of view. Invented in 1900 but not generally used on firearms until reliably illuminated versions were invented in the late 1970s (usually referred to by the abbreviation "reflex sight").

Riot Gun

A popular term for a short barreled repeating shotgun as frequently used in law enforcement and personal protection.

Factory Ammo

Ammunition that has been assembled by a commercial vendor of ammunition and sold in retail stores. This is as opposed to Hand loads which have been assembled by individuals and are not typically sold.

Prime

To prepare or charge a muzzle loader for firing.

Skeet

A shotgun shooting sport in which the competitors attempt to break aerial targets directed toward them or crossing in front of them from different angles and elevations. It is an Olympic shooting sport.

Three Gun

A shooting sport where cometitors use three different guns on each stage of the competion; shotgun, rifle and handgun.

Scope

A magnifying tube through which the shooter may see the target and aim the firearm. Scopes contain a reticle, commonly in the shape of a cross, which must be properly centered upon the target for accurate aim.

Bolt Action

A type of firearm action in which the guns's bolt is operated manually by the opening and closing of the breech (barrel) with a small handle. As the handle is operated, the bolt is unlocked, the breech is opened, the spent shell casing is withdrawn and ejected, the firing pin is cocked, and finally a new round/shell (if available) is placed into the breech and the bolt closed.

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."

Loaded

A firearm is loaded when a cartridge is in its firing chamber. However, for safety reasons all firearms are always treated as loaded at all times.

Headspace Gauge

Plugs of hardened steel, precisely machined in relation to the standard dimensional specifications of a given cartridge, normally in sets of three: "GO", "No-Go" and "Field". By loading these plug-gauges into the chamber in succession, one can check that the action should close on the "Go" gauge. It should not close on the "No-Go" gauge, but might were enough force to be used. And, it absolutely should not close on the "Field" gauge.

Side-By-Side

A shotgun with two barrels which are situated next to each other. Somtimes also abreviated as SxS.

Garniture

A deluxe set of several different associated weapons, being any combination of rifle, shotgun, various handguns, and possibly a knife or two, cased together with appropriate cleaning and loading tools.
