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.

Action (firearms)
In firearms terminology, an action is the functional mechanism of a breechloading firearm that handles (loads, locks, fires, extracts, and ejects) the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the ''lock'' (e.g. matchlock, wheellock, flintlock, and caplock). Actions can be categorized in several ways, including single action versus double action, break action versus lever-action, pump-action, bolt-action, among many other types. The term action can also include short, long, and magnum if it is in reference to the length of the rifle's receiver and the length of the bolt. The short action rifle usually can accommodate a cartridge length of or smaller. The long action rifle can accommodate a cartridge of , ...

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.

Magazine (firearms)
A magazine, often simply called a mag, is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridge (firearms), cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the gun barrel, barrel chamber (firearms), chamber by the firearm's moving action (firearms), action. The detachable magazine is sometimes colloquially referred to as a "clip (ammunition), clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine or cylinder. Magazines come in many shapes and sizes, from integral tubular magazines on lever-action and pump-action rifles and shotguns, that may hold more than five rounds, to detachable box magazines and drum magazines for automatic rifles and light machine guns, that may h ...

Semi-automatic Rifle
A semi-automatic rifle is a type of rifle that fires a single round each time the Trigger (firearms), trigger is pulled while automatically loading the next Cartridge (firearms), cartridge. These rifles were developed Pre-World War II, and were used throughout World War II. Rifles are firearms designed to be fired while held with both hands and braced against the shooter's shoulder for stability. Externally similar shotguns can fire multiple Shot (pellet), pellets simultaneously through a smoothbore, while rifle Gun barrel, barrels are Rifling, rifled to spin-stabilize individual bullets. The actions of semi-automatic rifles use a portion of the fired cartridge's energy to eject the spent casing and load a new round into the Chamber (firearms), chamber, readying the rifle to be fired again. This design differs from manually operated rifles such as Bolt action, bolt-action and Lever action, lever-action rifles, which need to chamber a cartridge manually before firing again, and ...

Rifle
A rifle is a long gun, long-barreled firearm designed for accurate shooting and higher stopping power, with a gun barrel, barrel that has a helical or spiralling pattern of grooves (rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used in warfare, law enforcement, hunting and shooting sports, target shooting sports. The invention of rifling separated such firearms from the earlier smoothbore weapons (e.g., arquebuses, muskets, and other long guns), greatly elevating their accuracy and general effectiveness. The raised areas of a barrel's rifling are called ''lands''; they make contact with and exert torque on the projectile as it moves down the bore, imparting a spin. When the projectile leaves the barrel, this spin persists and lends gyroscopic stability to the projectile due to conservatio ...

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 ...

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 ...

M1 Garand
The M1 Garand or M1 rifleOfficially designated as U.S. rifle, caliber .30, M1, later simply called Rifle, Caliber .30, M1, also called US Rifle, Cal. .30, M1 is a semi-automatic rifle that was the service rifle of the United States Army, U.S. Army during World War II and the Korean War. The rifle is chambered for the .30-06 Springfield cartridge and is named after its Canadian Americans, Canadian-American designer, John Garand. It was the first standard-issue autoloading rifle for the United States. By most accounts, the M1 rifle performed well. General George S. Patton called it "the greatest battle implement ever devised". The M1 replaced the (bolt-action) M1903 Springfield as the U.S. service rifle in 1936, and was itself replaced by the (selective fire, selective-fire) M14 rifle on 26 March 1958. Pronunciation Sources differ on the pronunciation of the M1 Garand. Some, such as General Julian Hatcher, Julian Hatcher's ''The Book of the Garand'' (1948), give , identical to ...

Repeating Firearm
A repeating firearm or repeater is any firearm (either a handgun or long gun) that is designed for multiple, repeated firings before the gun has to be reloaded with new ammunition. Unlike single-shot firearms, which can only hold and fire a single round of ammunition, a repeating firearm can store multiple cartridge (firearms), cartridges inside a magazine (firearms), magazine (as in pistols, rifles, or shotguns), a cylinder (firearms), cylinder (as in revolvers), or a belt (firearms), belt (as in machine guns), and uses a moving action (firearms), action to manipulate each cartridge into and out of the battery position (within the chamber (firearms), chamber and in alignment with the gun barrel#Bore, bore). This allows the weapon to be discharged repeatedly in relatively quick succession, before manually reloading the ammunition is needed. Typically the term "repeaters" refers to the more ubiquitous single-gun barrel, barreled variants. Multiple-barrel firearms such as derringe ...

Sniper Rifle
A sniper rifle is a high-precision, long range shooting, long-range rifle. Requirements include high accuracy, reliability, mobility, concealment, and optics, for anti-personnel weapon, anti-personnel, anti-materiel rifle, anti-materiel and surveillance uses by military snipers. The modern sniper rifle is a portable shoulder-fired rifle with either a bolt action or semi-automatic firearm, semi-automatic action (firearms), action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance Centerfire ammunition, centerfire cartridge (firearms), cartridge. History The Whitworth rifle was arguably the first long-range sniper rifle in the world. Designed in 1854 by Sir Joseph Whitworth, a prominent British engineer, it used barrels with hexagonal polygonal rifling, which meant that the projectile did not have to "bite" into the rifling grooves as with conventional rifling. His rifle was far more accurate than the Pattern 1853 Enfield, which ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolt (firearms)

Note the curved handle on the side for manual operation thumb"> Slide locked back on a Desert Eagle pistol, showing the gas-operated rotating bolt mechanism A bolt is the part of a repeating, breechloading firearm that blocks the rear opening (breech) of the barrel chamber while the propellant burns, and moves back and forward to facilitate loading/unloading of cartridges from the magazine. The firing pin and extractor are often integral parts of the bolt. The terms " breechblock" and "bolt" are often used interchangeably or without a clear distinction, though usually, a bolt is a type of breechblock that has a nominally circular cross-section. In most automatic firearms that use delayed blowback, recoil, or gas operation, the bolt itself is housed within the larger bolt carrier group (BCG), which contains additional parts that receives rearward push from a gas tube ( direct impingement) or a gas piston (short-stroke o ...

Firing Pin
A firing pin or striker is a part of the firing mechanism of a firearm that impacts the primer in the base of a cartridge and causes it to fire. In firearms terminology, a striker is a particular type of firing pin where a compressed spring acts directly on the firing pin to provide the impact force rather than it being struck by a hammer. The terms may also be used for a component of equipment or a device which has a similar function. Such equipment or devices include: artillery, munitions and pyrotechnics. Firearms The typical firing pin is a thin, simple rod with a hardened, rounded tip that strikes and crushes the primer. The rounded end ensures the primer is indented rather than pierced (to contain propellant gasses). It sits within a hole through the breechblock and is struck by the hammer when the trigger is "pulled". A light firing-pin spring is often used to keep the firing pin rearward. It may be termed a ''firing-pin return spring'', since it returns it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
