19 Other Firearms Definitions You Need To Know


Checkered Butt

Checkering, applied to the otherwise-unfinished butt end of a gunstock.

Ammo

Slang word abreviation for Ammunition.

Percussion Cap

A small metal explosive-filled cup which is placed over the nipple of a percussion firearm. As the cap is struck by the hammer, it explodes and sends a flame through the flashhole in the nipple to the main powder charge.

Reset Point

The point of the trigger's return at which the gun's internal mechanisms are ready to fire another round.

C&R

Abbreviation for Curio and Relic

Monte Carlo Comb

The Monte Carlo comb came to rifles via shotgun stocks. It rises well above the ordinary comb line of the stock at the butt and tapers downward toward the point of the comb. This raised portion of the stock lifts the face of the shooter and his or her line of sight well above the standard elevation provided by the classic style. However, the same amount of drop is maintained at the buttstock. A shooter with a long neck who often has trouble getting his or her face down far enough on the comb of the regular stock benefits from the Monte Carlo style.

Turn-Bolt Action

A bolt action which is locked by pressing the bolt handle in and down, thereby turning its locking lugs into the receiver.

Crosshairs

The cross-shaped object seen in the center of a firearm scope. Its more-proper name is reticle.

Silhouette Shooting

A handgun or rifle shooting sport in which the competitors attempt to knock over metallic game-shaped targets at various ranges.

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.

Close Quarters Combat

a type of fighting in which small units engage the enemy with personal weapons at very short range, potentially to the point of hand-to-hand combat or fighting with hand weapons such as swords or knives.

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.

Pigeon Gun

A double-barrel shotgun, with relatively tight choke boring and a relatively high-combed stock used for shooting live pigeons (euphemistically known as flyers) which normally rise when released. To better absorb recoil, a pigeon gun is normally heavier than a field gun as one shoots heavy loads and walks only a little. Because of the inevitable expense of this shooting discipline, pigeon guns are often built to a high standard of quality and reliability in deluxe grades with highly figured walnut stocks and fine engraving.

Point Blank Shooting

Shooting a target at a very very close range.

Capper

A hand tool used in the field for inserting live and removing spent primers from cartridges.

Erosion

The wearing away of a barrel's metal surface by a bullet or shot charge or by the heat of powder gases.

Casket Magazine

A quad stack box magazine.

Gas Operated

The superheated air created by burning powder. A gas-operated firearm is one that uses the energy from these superheated gases to work the action in semi-automatic and automatic guns.

Loaded Chamber Indicator

A mechanical device that protrudes from the gun when a round is in position ready to be fired, giving a visual and tactile indication that the gun is loaded.
