Anson & Deeley Action

A type of internal hammer side by side shotgun boxlock action. It was patented in 1875 and is the essence of simplicity utilizing only two springs and three moving parts (per barrel). One of the most successful action designs ever, and still produced to this day by most SxS shotgun manufacturers.


19 Other Firearms Definitions You Need To Know


Holdopen Toplever

A catch built into the receiver of a break-open gun to keep the toplever in its extreme right position when the barrels are removed. This device makes it slightly easier to remount the barrels. As the barrels are mounted and the breech closed, the barrels contact some kind of release pin (marked with the arrow) and the toplever automatically returns to the center locked position. Because, however, it requires a separate act to find and to depress this tiny tab to re-center the toplever on a broken-down gun, this feature may be irritating when trying to put a gun away in its case.

Quaker Gun

Not really a gun at all. During the U.S. Civil War, both sides would take tree branches or tree trunks, paint them black, and position them so that they appeared to be rifles or artillery pieces. By doing so, they could fool the other side into believing that they had more artillery than they really did.

Centerfire (Center Fire)

A cartridge with its primer located in the center of the base of the case.

Open Bolt

A type of firearm in which the action is in the open position and the chamber empty prior to firing. When the trigger is pressed the bolt moves forward, chambering a cartridge and firing it and returning to the open position. When firing is stopped the bolt remains open and the chamber empty.

Telescopic Sight

An optical sight, offering some magnification, often variable, with some kind of adjustable aiming grid inside (a reticle), which when mounted on a firearm, usually a rifle, makes sighting easier.

Trigger Pull

The entire process of moving the trigger from its forward-most position to its rearward-most position, causing the hammer to fall and the shot to fire.

Hot Range

A condition (status) of a shooting range that shooters may commence to fire.

Expanding Bullet

An expanding bullet is a bullet designed to expand on impact, increasing in diameter to limit penetration and/or produce a larger diameter wound. The two typical designs are the hollow point bullet and the soft point bullet. See also Dum-Dum Bullet

Patch

A small piece of leather or cloth. A patch can refer to the wadding used in loading a muzzle loading firearms or the piece of cloth used to clean a firearm bore.

LC

Lever Action

A type of firearm action which uses a lever located around the trigger guard area, (often including the trigger guard itself) to load fresh cartridges into the chamber of the barrel when the lever is worked.

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.

Fouling

The accumulation of unwanted material on solid surfaces. The fouling material can consist of either powder, lubrication residue, or bullet material such as lead or copper.

Chapman Stance

The Chapman stance uses the same push-pull tension which defines the Weaver, but instead of both elbows being bent, the gun side elbow is held straight and locked in place. Assuming a right-handed shooter, the right arm is punched straight out, while the left elbow is bent and the left hand pulls back to provide tension. As a result of this change, Chapman gets its stability from both muscle and skeletal support. This makes it a little more friendly than Weaver for those who lack upper-body muscle strength.

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.

CCW

Abbreviation for Concealed Carry Weapon

Wad

A felt, paper, cardboard or plastic disk that is used in a shotshell. Also in muzzle loading, a piece of cloth used to seal the bullet in the barrel. It's purpose and function is the same as a shotgun wad.

Chain Gun

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