The Definition of 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As the handle is operated, the bolt is unlocked, the breech is opened, the spent shell casing is withdrawn and ejected,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.

Sometimes spelled Bi-Pod.
A support device that is similar to a tripod or monopod, but with two legs. On firearms, bipods are commonly used on rifles to provide a forward rest and reduce motion.
The bipod permits the operator to rest the weapon on the ground, a low wall, or other object, reducing operator fatigue and permitting increased accuracy.
An extra-deep magazine typical of large calibre rifles for dangerous game. The line of the underside of the wrist does not carry straight forward as with ordinary rifles.
Rather the rear of the magazine aligns more towards the center of the forward edge of the triggerguard,
typically allowing at least one extra cartridge to be carried.
German for "short." Seen as part of a cartridge designation. On some German manufactured guns that use .380 ACP, the designated caliber is 9mm Kurtz (9mm Short), which is also the same as the Italian 9mm Corto
The first shot from a rifle that has been cleaned, and not fired recently may go to a different point of impact, for the same point of aim than a rifle that has been fired recently.
This first shot is referred to as a shot from a cold, clean, bore.
The four rules of firearms safety,were originally introduced in the early 1900's by various shooting education sources (with varying phrasing, but same implications), they apply every single time a firearm is handled in any way or for any reason. The NRA
teaches the Three Rules of Safe Gun Handling.
Rule One: All guns are always loaded. (Treat all guns as if they are loaded, no matter what!)
Rule Two: Never point your firearm at anything you are not willing to destroy.
Rule Three: Never put your finger on the trigger unless your sights are on target (and you have made the decision to fire).
Rule Four: Be sure of your target and what is behind it.
A firearm loaded through the breech.

A rib extension on a break-open gun, ending in a circular or semi-circular shape in plan (resembling the head of a doll),
mating into a similarly-shaped recess in the top of the receiver, designed to resist the tendency of
the barrels to pull away from the standing breech when firing.
Because an action's centerpoint of flexing when firing is at the base of the standing breech, not at the hingepin, a passive doll's
head extension makes an effective extra fastener, even without additional mechanical locks operated by the opening lever.
The earliest type of gun, now also popular as modern-made replicas, in which blackpowder and projectile(s) are
separately loaded in through the muzzle. The term is often applied to cap-and-ball revolvers where the loading is
done not actually through the muzzle but through the open ends of the cylinder's chambers.
A bullet not covered by a metal jacket or patch.
A variety of pneumatic gun that propels projectiles by means of compressed air or other gas, in contrast to firearms, which use a propellant charge.
Both the rifle and pistol forms (air rifle and air pistol) typically propel metallic projectiles, either pellets, or BBs. Certain types of air guns, usually rifles, may also propel arrows.
A system of firearms ignition, in general use circa 1660 - 1825, whereby the pull of a trigger releases a sear from a notch in a spring-loaded hammer,
which holding a properly knapped piece of flint, strikes a vertical slab of steel (called a frizzen) scraping off tiny molten particles of the steel,
and pushing it forward causes an integral flashpan cover to open forward, exposing a bit of fine gunpowder below, which when contacted by the falling sparks,
ignites and sends a flash of fire through the touchhole, into the loaded breech setting off the main charge and firing the gun.
The Flintlock system was supplanted by the Percussion system around 1820.
An inert ammunition-shaped object, used in practice to simulate misfeeds and other malfunctions. Some folks also use them during dry fire practice to cushion the firing pin as it strikes.
The Soviet Union's standard military and police side arm from 1951 to 1991 replacing the Tokarev TT-33 semi-automatic pistol and the Nagant M1895 revolver.
Designed by Nikolay Fyodorovich Makarov, it is a blowback operated semiautomatic pistol which fires the 9x18mm Makarov cartridge, and holds 8 rounds in the magazine.
The part of a revolver that holds cartridges in
separate chambers radially around a central hingepin. The cylinder revolves as
the handgun is cocked, , either to the left or to the right depending on the gun maker's design,
bringing each successive cartridge into position, and
locked into alignment with the barrel for firing.
Circular steel fittings, about 1/2 inch in diameter, screwed into the breech face of a gun and through which the firing pins pass.
Firing pin bushings allow the convenient replacement of broken firing pins. They also allow the renewal of an older gun where, over the decades,
leakage of high-pressure gas from corrosive primers has eroded the breech face around the firing pins; and replacing these bushings with new ones,
slightly oversized can compensate for a situation where proper headspace has been compromised.
