Extractor (firearms)
file:ShotgunAction.JPG, A view of the break-action of a typical double-barrelled shotgun, with the action open and the scalloped triangularly shaped extractor visible at the base of the two barrels. The opening lever and the safety catch are visible In breechloading firearms, an extractor is an action (firearms), action component that serves to remove spent cartridge case, casings of previously fired cartridge (firearm), cartridges from the chamber (firearms), chamber, in order to vacate the chamber for loading a fresh round of ammunition. In repeating firearms with moving bolt (firearm), bolts, the extractor is often one or a set of hook-like flanges on the bolt head that grabs onto the casing's rim (firearms), rim, so when the bolt moves rearwards the casing is pulled out of the chamber. It is typically aided by a protruding ejector in the receiver (firearms), receiver or the bolt, which provides an opposite counter-push that couple (mechanics), couples with the extractor pull to ...

Double-barrel Shotgun
A double-barreled shotgun, also known as a double shotgun, is a Break action, break-action shotgun with two parallel gun barrel, barrels, allowing two single shots that can be fired simultaneously or sequentially in quick succession. Construction Modern double-barreled shotguns, often known as ''doubles'', are almost universally break action, with the barrels hinge down at the rear to expose the breech ends for unloading and reloading. Since there is no reciprocating motion, reciprocating action (firearms), action needed to eject and reload the shotgun shell, shells, doubles are more compact than repeating designs such as pump action, lever action, bolt action, or semi-automatic shotgun, self-loading shotguns. Barrel configuration Double-barreled shotguns (specifically break-action), come in two basic configurations: * side-by-side (S×S) — the two barrels are arranged horizontally; * over-and-under (O/U) — the two barrels are arranged vertically. The original double-ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Rifles
The double rifle, also known as a double-barreled rifle, is a rifle with two barrels mounted parallel to each other that can be fired simultaneously or sequentially in quick succession. Synonymous with big game hunting found primarily in Africa and Asia, the double rifle is a sporting weapon with very little military heritage. Design The double rifle is usually handcrafted and is considered by many to be the pinnacle of sporting rifle design. It is not designed for long-range accuracy but instead for the security of an immediate second shot. Double rifles are similar to double-barreled shotguns. Action As with double-barrelled shotguns, modern double rifles are all made with either sidelock or boxlock actions, although occasionally old hammer rifles can be found. The majority of double rifles have been built on the boxlock actions as it is a simpler design with fewer moving parts that can fail. Consequently, it has an outstanding reputation for reliability. The sidelock action ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shotgun
A shotgun (also known as a scattergun, peppergun, or historically as a fowling piece) is a long gun, long-barreled firearm designed to shoot a straight-walled cartridge (firearms), cartridge known as a shotshell, which discharges numerous small spherical projectiles called shot (pellet), shot, or a single solid projectile called a shotgun slug, slug. Shotguns are most commonly used as smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting Sabot (firearms), sabot slugs (slug barrels) are also available. Shotguns come in a wide variety of calibers and Gauge (firearms), gauges ranging from 5.5 mm (.22 inch) to up to , though the 12-gauge (18.53 mm or 0.729 in) and 20-gauge (15.63 mm or 0.615 in) bores are by far the most common. Almost all are breechloading, and can be single barreled, double-barreled shotgun, double barreled, or in the form of a combination gun. Like rifles, shotguns also ...

Single-shot
In firearm designs, the term single-shot refers to guns that can hold only a single round of ammunition inside and thus must be reloaded manually after every shot. Compared to multi-shot repeating firearms ("repeaters"), single-shot designs have no moving parts other than the trigger (firearms), trigger, hammer (firearms), hammer/firing pin or frizzen, and therefore do not need a sizable receiver (firearms), receiver behind the gun barrel, barrel to accommodate a moving action (firearms), action, making them far less complex and more robust than revolvers or magazine (firearm), magazine/ammunition belt, belt-fed firearms, but also with much slower rate of fire, rates of fire. The history of firearms began with muzzleloader, muzzleloading single-shot firearms such as the hand cannon and arquebus, then multiple-barrel firearm, multi-barreled designs such as the derringer appeared, and eventually many centuries passed before breechloading repeating firearms became commonplace.

Revolver
A revolver is a repeating handgun with at least one barrel and a revolving cylinder containing multiple chambers (each holding a single cartridge) for firing. Because most revolver models hold six cartridges before needing to be reloaded, revolvers are commonly called six shooters or sixguns. Due to their rotating cylinder mechanism, they may also be called wheel guns. Before firing, cocking the revolver's hammer partially rotates the cylinder, indexing one of the cylinder chambers into alignment with the barrel, allowing the bullet to be fired through the bore. By sequentially rotating through each chamber, the revolver allows the user to fire multiple times until having to reload the gun, unlike older single-shot firearms that had to be reloaded after each shot. The hammer cocking in nearly all revolvers is manually driven and can be cocked either by the user using the thumb to directly pull back the hammer (as in single-action), or via internal linkage relaying t ...

Fully Automatic
An automatic firearm or fully automatic firearm (to avoid confusion with semi-automatic firearms) is a self-loading firearm that continuously chambers and fires rounds when the trigger mechanism is actuated. The action of an automatic firearm is capable of harvesting the excess energy released from a previous discharge to feed a new ammunition round into the chamber, and then igniting the propellant and discharging the projectile (either bullet, shot, or slug) by delivering a hammer or striker impact on the primer. If ''both'' the feeding and ignition procedures are automatically cycled, the weapon will be considered "fully automatic" and will fire continuously as long as the trigger is kept depressed and the ammunition feeding (either from a magazine or a belt) remains available. In contrast, a firearm is considered " semi-automatic" if it only automatically cycles to chamber new rounds (i.e. self-loading) but does not automatically fire off the shot unless the user ma ...

Semi-automatic Firearm
A semi-automatic firearm, also called a self-loading or autoloading firearm ( fully automatic and selective fire firearms are also variations on self-loading firearms), is a repeating firearm whose action mechanism automatically loads a following round of cartridge into the chamber and prepares it for subsequent firing, but requires the shooter to manually actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot (in the form of recoil or high-pressure gas expanding within the bore) to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, and allow it to "reset", before pulling the trigger again to fire off the next round. As a result, each trigger p ...

Pump-action
Pump action is a type of manual firearm action that is operated by moving a sliding handguard on the gun's forestock. When shooting, the sliding forend is pulled rearward to eject any expended cartridge (firearms), cartridge and typically to cock the hammer (firearms), hammer or firing pin, striker, and then pushed forward to load a new cartridge into the chamber (firearms), chamber. Most pump-action firearms use an integral tubular magazine, although some do use detachable box magazines. Pump-action firearms are typically associated with shotguns, although it has also been used in rifles, grenade launchers, and other types of firearms. A firearm using this operating mechanism is colloquially referred to as a pumpgun. Because the forend is manipulated usually with the support hand, a pump-action firearm is much faster than a bolt-action rifle, bolt-action and somewhat faster than a lever-action, as it does not require the trigger (firearms), trigger hand to be removed from the ...

Lever-action
The toggle-link action used in the iconic Winchester Model 1873 rifle, one of the most famous lever-action firearms Picture showing a Volcanic Pistol A lever action is a type of action for repeating firearms that uses a manually operated cocking handle located around the trigger guard area (often incorporating it) that pivots forward to move the bolt via internal linkages, which will feed and extract cartridges into and out of the chamber, and cock the firing pin mechanism. This contrasts to other type of repeating actions such as the bolt-action, pump-action, semi-automatic, fully automatic, and/or burst mode actions. A firearm using this operating mechanism is colloquially referred to as a levergun. Most lever-action firearms are rifles, but some lever-action shotguns and a few pistols have been made. The Winchester Model 1873 rifle is one of the most famous lever-action firearms, but many manufacturers (notably Henry Repeating Arms and Marlin Firearms) also produce l ...

Bolt-action
Bolt action is a type of manual Action (firearms), firearm action that is operated by ''directly'' manipulating the bolt (firearms), turn-bolt via a cocking handle, bolt handle, most commonly placed on the right-hand side of the firearm (as most users are right-handed). The majority of bolt-action firearms are rifles, but there are also some variants of shotguns and handguns that are bolt-action. Bolt action firearms are generally repeating firearms, but many single-shot designs are available particularly in shooting sports where single-shot firearms are mandated, such as most Olympic and International Shooting Sport Federation, ISSF rifle disciplines. From the late 19th century all the way through both World Wars, bolt action rifles were the standard infantry service rifle, service weapons for most of the world's military forces, with the exception of the United States Armed Forces, who used the M1 Garand Semi-automatic rifle.
