Pancor Jackhammer
The Pancor Corporation Jackhammer is a 12-gauge, blow-forward gas-operated bullpup automatic shotgun designed in 1984 and patented in 1987. Only three working prototypes of the Jackhammer were built, but despite notable interest, legal and financial issues meant the Jackhammer never entered production, though it was notably popular as a prop weapon in films, television shows, and video games in the 1990s and 2000s, owing to its futuristic design and unusual operation. Development The Jackhammer was designed by John A. Anderson, who formed the company Pancor Industries in New Mexico. Anderson, a Korean War veteran, found the pump action shotguns he used in the war to be awkward and time consuming to reload, and believed he could design a better shotgun without this flaw. Testing was conducted by HP White Labs in destructive tests that destroyed two of the three prototypes. These models reportedly had of material removed with increased stamping instead of casting and a differen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bullpup
A bullpup firearm is one with its firing grip located in front of the Chamber (firearms), breech of the weapon, instead of behind it. This creates a weapon with a shorter overall length for a given barrel length, and one that is often lighter, more compact, concealable, and more maneuverable than a conventionally configured firearm. Where it is desirable for troops to be issued a more compact weapon, the use of a bullpup configuration allows for barrel length to be retained, thus preserving muzzle velocity, range, and ballistic effectiveness. The bullpup concept was first tested militarily in 1901 with the British Thorneycroft carbine, but it was not until the Cold War that more successful designs and improvements led to wider adoption. In 1977, the Austrian Federal Army, Austrian Army became the first military force in the world to adopt a bullpup rifle, the Steyr AUG, as a service rifle, principal combat weapon. Since then the militaries in many countries have followed suit w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jane's Information Group
Janes is a global open-source intelligence company specialising in military, national security, aerospace and transport topics, whose name derives from British author Fred T. Jane. History Jane's Information Group was founded in 1898 by Fred T. Jane, who had begun sketching ships as an enthusiast naval artist while living in Portsmouth. This gradually developed into an encyclopedic knowledge, culminating in the publishing of Jane's Fighting Ships, ''All the World's Fighting Ships'' (1898). The company then gradually branched out into other areas of military expertise. The books and trade magazines published by the company are often considered the ''de facto'' public source of information on warfare and transportation systems. Based in Greater London for most of its existence, the group was owned by the Thomson Corporation, the Woodbridge Company, then IHS Markit, before being acquired by Montagu Private Equity in 2019.

Land Mine
A land mine, or landmine, is an explosive weapon often concealed under or camouflaged on the ground, and designed to destroy or disable enemy targets as they pass over or near it. Land mines are divided into two types: anti-tank mines, which are designed to disable tanks or other vehicles; and anti-personnel mines, designed to injure or kill people. Land mines are typically pressure activated, exploding automatically when stepped on by a person or driven over by a vehicle, though alternative detonation mechanisms are sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Land mines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their indiscriminate nature and their potential to remain dangerous many years after a conflict has ended, harming civilians and the economy. With pressure from a number of campaign gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nagant M1895
The Nagant M1895 is a seven-shot, gas-seal revolver designed and produced by Belgian industrialist Fabrique d'armes Émile et Léon Nagant, Léon Nagant for the Russian Empire. The Nagant M1895 was chambered for a proprietary cartridge, 7.62×38mmR, and features a gas-seal system, in which the cylinder moves forward when the gun is cocked, to close the gap between the cylinder and the Gun barrel, barrel, providing a boost to the muzzle velocity of the bullet and allowing the weapon to be Suppressor, suppressed. Its design would inspire the Pieper M1893 carbine and Steyr 1893 revolver. History The Nagant was designed by Léon Nagant, whose brother Émile had also taken part in designing the Mosin–Nagant rifle.

Breech-loading Weapon
A breechloader is a firearm in which the user loads the ammunition from the breech end of the barrel (i.e., from the rearward, open end of the gun's barrel), as opposed to a muzzleloader, in which the user loads the ammunition from the ( muzzle) end of the barrel. The vast majority of modern firearms are generally breech-loaders, while firearms made before the mid-19th century were mostly smoothbore muzzle-loaders. Only a few muzzleloading weapons, such as mortars, rifle grenades, some rocket launchers, such as the Panzerfaust 3 and RPG-7, and the GP series grenade launchers, have remained in common usage in modern military conflicts. However, referring to a weapon explicitly as breech-loading is mostly limited to weapons where the operator loads ammunition by hand (and not by operating a mechanism such as a bolt-action), such as artillery pieces or break-action small arms. Breech-loading provides the advantage of reduced reloading time because it is far quicker to load t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recoil Operation
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. History The earliest mention of recoil used to assist the loading of firearms is sometimes claimed to be in 1663 when an Englishman called Palmer proposed to employ either it or gases tapped along a barrel to do so. However no one has been able to verify this claim in recent times, although there is another automatic gun that dates from the same year, but its type and method of operation are unknown. Recoil-operation, if it was invented in 1663, would then lie dormant until the 19th century, when a number of inventors started to patent designs featuring recoil operation; this was due to the fact that the integrated disposable cartridge (both bullet and propellant in one easily interchangeable unit) made these designs vi ...

Webley–Fosbery Automatic Revolver
The Webley–Fosbery Self-Cocking Automatic Revolver is a recoil-operated automatic revolver designed by Lieutenant Colonel George Vincent Fosbery VC and produced by the Webley & Scott company from 1901 to 1924. The revolver is easily recognisable by the zig-zag grooves on the cylinder. The handgun was offered in both .455 and .38 calibers and, somewhat unique for a revolver, features a manual thumb safety. History Semi-automatic pistols were just beginning to appear when Colonel Fosbery (1832–1907) devised a revolver that cocked the hammer and rotated the cylinder by sliding the action, cylinder and barrel assembly back on the frame. The prototype was a modified Colt Single Action Army revolver. However, Colt was uninterested in the automatic design. Fosbery patented his invention 16 August 1895 and further improvements were patented in June and October 1896. Fosbery took his design to P. Webley & Son of Birmingham. P. Webley & Son, which merged with W.C. Scott & Sons and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
