A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries.
Gun laws and policies, collectively referred to as firearms regulation or gun control, regulate the manufacture, sale, transfer, possession, modification, and use of small arms by civilians. Laws of some countries may afford civilians a right to keep and bear arms, and have more liberal gun laws than neighboring jurisdictions. Countries that regulate access to firearms will typically restrict access to certain categories of firearms and then restrict the categories of persons who may be granted a license for access to such firearms. There may be separate licenses for hunting, sport shooting, self-defense, collecting, and concealed carry, with different sets of requirements, permissions, and responsibilities.
A revolver is a repeating handgun that has at least one barrel and uses a revolving cylinder containing multiple chambers for firing. Because most revolver models hold up to six cartridges, before needing to be reloaded, revolvers are commonly called six shooters.
A shotgun is a long-barreled firearm designed to shoot a straight-walled cartridge known as a shotshell, which discharges numerous small spherical projectiles called shot, or a single solid projectile called a 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 slugs are also available.
A sawed-off shotgun is a type of shotgun with a shorter gun barrel—typically under 18 inches (46 cm)—and often a shortened or absent stock. Despite the colloquial term, barrels do not, strictly speaking, have to be shortened with a saw. Barrels can be manufactured at shorter lengths as an alternative to traditional, longer barrels. This makes them easier to transport and conceal due to their smaller profile and lighter weight. The design also makes the weapon easy to maneuver in cramped spaces, a feature sought by military close-quarters combat units and law enforcement SWAT team users. As a result of the shorter barrel length, any sawn-off shotgun with a magazine tube will have its capacity reduced.
The pepper-box revolver or simply pepperbox is a multiple-barrel firearm, mostly in the form of a handgun, that has three or more gun barrels in a coaxially revolving mechanism. Each barrel holds a single shot, and the shooter can manually rotate the whole barrel assembly to sequentially index each barrel into alignment with the lock or hammer, similar to rotation of a revolver's cylinder.
In firearms, the chamber is the cavity at the back end of a breechloader's barrel or cylinder, where the cartridge is inserted before being fired. The rear opening of the chamber is the breech, and is sealed by the breechblock or the bolt.
A gun barrel is a crucial part of gun-type weapons such as small firearms, artillery pieces, and air guns. It is the straight shooting tube, usually made of rigid high-strength metal, through which a contained rapid expansion of high-pressure gas(es) is used to propel a projectile out of the front end (muzzle) at a high velocity. The hollow interior of the barrel is called the bore, and the diameter of the bore is called its caliber, usually measured in inches or millimetres.
The ArmaLite AR-10 is a 7.62×51mm NATO battle rifle designed by Eugene Stoner in the late 1950s and manufactured by ArmaLite. When first introduced in 1956, the AR-10 used an innovative combination of a straight-line barrel/stock design with phenolic composite, a new patent-filed gas-operated bolt and carrier system and forged alloy parts resulting in a small arm significantly easier to control in automatic fire and over 1 lb (0.45 kg) lighter than other infantry rifles of the day. Over its production life, the original AR-10 was built in relatively small numbers, with fewer than 10,000 rifles assembled. However, the ArmaLite AR-10 would become the progenitor for a wide range of firearms.
The Remington Model 870 is a pump-action shotgun manufactured by Remington Arms Company, LLC. It is widely used by the public for shooting sports, hunting and self-defense, as well as by law enforcement and military organizations worldwide.
A shotgun slug is a heavy projectile made of lead, copper, or other material and fired from a shotgun. Slugs are designed for hunting large game, and other uses, particularly in areas near human population where their short range and slow speed helps increase safety margin. The first effective modern shotgun slug was introduced by Wilhelm Brenneke in 1898, and his design remains in use today. Most shotgun slugs are designed to be fired through a cylinder bore, improved cylinder choke, rifled choke tubes, or fully rifled bores. Slugs differ from round ball lead projectiles in that they are stabilized in some manner.
The USAS-12 is an automatic shotgun manufactured in South Korea by Daewoo Precision Industries since the 1980s.
The Armsel Striker, also known as the Sentinel Arms Co Striker-12, Protecta, Protecta Bulldog and SWD Street Sweeper is a 12-gauge shotgun with a revolving cylinder that was designed for riot control and combat.
The ArmaLite AR-7 Explorer is a semi-automatic firearm in .22 Long Rifle caliber, developed in 1959 from the AR-5 that was adopted by the U.S. Air Force as a pilot and aircrew survival weapon. The AR-7 was adopted and modified by the Israeli Air Force as an aircrew survival weapon in the 1980s.
Break action is a type of firearm action in which the barrel or barrels are hinged much like a door and rotate perpendicularly to the bore axis to expose the breech and allow loading and unloading of cartridges. A separate operation may be required for the cocking of a hammer to fire the new round. There are many types of break-action firearms; break actions are universal in double-barreled shotguns, double-barreled rifles, combination guns, and are commonly found in single shot pistols, rifles, shotguns, including flare guns, grenade launchers, air guns, and some older revolver designs. They are also known as hinge-action, break-open, break-barrel, break-top, or, on old revolvers, top-break actions.
The M6 Aircrew Survival Weapon was a specially-made .22 Hornet over .410 bore combination gun issued to United States Air Force aircrews to help forage for food in the event of a plane crash. It was issued from 1952 until the early 1970s, in conjunction with the M4 Survival Rifle. Plans to replace both with the ArmaLite AR-5 never came to fruition and in 2018 was instead replaced with the GAU-5A Aircrew Self Defense Weapon in some instances.
Armas Ugartechea is a Basque Spanish manufacturer of guns and rifles located in Eibar, is a privately held Spanish firearms manufacturing company. Its firearms are used worldwide for a variety of sporting and hunting purposes. It produces several models of double-barreled shotgun. It is devoted to the craft manufacturing of fine hunting shotguns and is the heir of a long craftsman tradition that has cleverly incorporated new technologies in the production of its guns, and, at the same time, keeping its traditional know how. It was the first Spanish company to start making under and over barrel guns. I. Ugartechea is well known for the quality of its work both at home and abroad. Is one of the few gunmakers to produce its own barrels, flawless at best. A present, Armas Ugartechea sells its guns worldwide. Among its customers are heads of state and monarchs from several countries, as well as top hunters and crack shots. The Ugartechea Family is still in charge of the company which is a basic principle, as they are the ones who know better how to optimize the manufacture of these firearms, which combine with craftsman work the best technology.
The following are terms related to firearms and ammunition topics.
Recoil operation is an operating mechanism used to implement locked breech, autoloading firearms. Recoil operated firearms use the energy of recoil to cycle the action, as opposed to gas operation or blowback operation using the pressure of the propellant gas.
An AR-15–style rifle is any lightweight semi-automatic rifle based on or similar to the Colt AR-15 design. The Colt model removed the selective fire feature of its predecessor, the original ArmaLite AR-15, itself a scaled-down derivative of the AR-10 design by Eugene Stoner.
