Colt ACR
The Colt ACR was Colt's entry in the U.S. DoD Advanced Combat Rifle program, which concluded with the result that none of the entrants achieved enough of an improvement over the M16 to be worth the cost. The Colt ACR was not a total loss, however; the scope went on to be offered by Elcan as the C79, a version of which was eventually adopted as the M145 Machine Gun Optic used on a number of firearms, especially those from Diemaco (now Colt Canada). Overview The main differences of the Colt ACR and the M16A2 is the distinctive furniture. The handguard included a heat-resistant inner lining, vent holes for lightening and air cooling with a thickened ring around the front end to act as a handstop. This was topped with an elevated sight track rib with a white stripe to improve fast target acquisition. The pistol grip was longer and of a different profile than a traditional M16A2, and the rifle featured ambidextrous fire control selectors, removable scope and a streamlined 6 posit ...

M16 Rifle
The M16 rifle (officially designated Rifle, Caliber 5.56 mm, M16) is a family of military rifles adapted from the ArmaLite AR-15 rifle for the United States military. The original M16 rifle was a 5.56×45mm automatic rifle with a 20-round magazine. In 1964, the M16 entered US military service and the following year was deployed for jungle warfare operations during the Vietnam War. In 1969, the M16A1 replaced the M14 rifle to become the US military's standard service rifle.Urdang, p. 801. The M16A1 incorporated numerous modifications including a bolt-assist, chrome-plated bore, protective reinforcement around the magazine release, and revised flash hider. In 1983, the US Marine Corps adopted the M16A2 rifle and the US Army adopted it in 1986. The M16A2 fires the improved 5.56×45mm (M855/SS109) cartridge and has a newer adjustable rear sight, case deflector, heavy barrel, improved handguard, pistol grip and buttstock, as well as a semi-auto and three-round burst fire sele ...

Assault Rifles Of The United States
An assault is the act of committing physical harm or unwanted physical contact upon a person or, in some specific legal definitions, a threat or attempt to commit such an action. It is both a crime and a tort and, therefore, may result in criminal prosecution, civil liability, or both. Generally, the common law definition is the same in criminal and Assault (tort), tort law. Traditionally, common law legal systems have separate definitions for assault and Battery (crime), battery. When this distinction is observed, battery refers to the actual bodily contact, whereas assault refers to a credible threat or attempt to cause battery. Some jurisdictions combined the two offences into a single crime called "assault and battery", which then became widely referred to as "assault". The result is that in many of these jurisdictions, assault has taken on a definition that is more in line with the traditional definition of battery. The legal systems of Civil law (legal system), civil law ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Assault Rifles
An assault rifle is a rifle that uses an intermediate cartridge, a detachable magazine, and can switch between semi-automatic/fully automatic fire. Assault rifles are currently the standard service rifles in most modern armies. Some rifles listed below such as the AR15 also come in semi-auto models which would not belong under the term "Assault Rifle". Definition By strict definition, a firearm must have the following characteristics to be considered an assault rifle: * It must be an individual weapon; * It must be capable of selective fire, which means it has the capacity to switch between semi-automatic and burst/fully automatic fire; * It must have an intermediate-power cartridge: more power than a pistol but less than a standard rifle or battle rifle. For full-power automatic rifles, see List of battle rifles; * Its ammunition must be supplied from a detachable box magazine; * It should have an effective range of at least . Rifles that meet most of these criteria, but not a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buck And Ball
Buck and ball was a common load for muzzle-loading muskets, and was frequently used in the American Revolutionary War and into the early days of the American Civil War. The load usually consisted of a .50 to .75 caliber round lead musket ball that was combined with three to six buckshot pellets. Construction By the 1840s, buck and ball was issued in prepared paper cartridges that combined the projectiles with the black powder propellant charge to facilitate rapid loading of the weapon. Like any other paper cartridge, the rear of the cartridge would be torn open to expose the powder, which would be loaded, and the remaining paper, ball, and buckshot would be rammed down on top. Purpose The intent of the buck and ball load was to combine the devastating impact of a .50 to .75 caliber ball with the spreading pattern of a shotgun. The combination served to greatly improve the hit probability of the smoothbore musket. In combat, especially at closer ranges, the buckshot would re ...

Project Abakan
Project Abakan was a Soviet/Russian advanced assault rifle program in rival to the US Advanced Combat Rifle that took place between 1980 and 1994. History The 1960s ushered a new generation of assault rifles with the introduction of smaller calibers. U.S. military analysis of combat during the Second World War showed that a greater volume of fire at shorter ranges was more significant than long range accuracy. They decided that a smaller caliber would be more effective in most conditions, because the soldier could carry more ammunition. In 1963, United States adopted the M16 Rifle and the smaller 5.56×45mm cartridge to replace the M14 Rifle and larger 7.62×51mm. In 1980, NATO adopted the 5.56mm as the standard issue rifle cartridge. In 1974, the Soviet Army also replaced the AKM with the AK-74 assault rifle chambered for the new smaller 5.45×39mm caliber. In spite of the smaller caliber and many other improvements the AK-74 failed to overcome the major shortcoming of its p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colt Automatic Rifle
The Colt Automatic Rifle or Colt Light Machine Gun is a 5.56 mm NATO, open-bolt, full-automatic-only firearm developed by Colt Defense. It is based on the M16A2/A4, and has a distinctive squared-off handguard, vertical grip, carrying handle and integrated bipod. It is one of many squad automatic weapon-type firearms that have been developed from the Armalite AR-15 that use the Stoner bolt and carrier piston system. The family name was derived from the original AR-15 by adding "Colt", resulting in the CAR-15, to stand for Colt Automatic Rifle. The CAR-15 weapons system consisted of the AR-15 and five variations, including the Colt Machine Gun and CAR-15 Heavy Assault Rifle. Overview The Colt Automatic Rifle is the name of a current product, but Colt has developed a number of similar weapons since the company obtained the rights to produce the Armalite AR-15 family at the end of the 1950s. Originally known as the Colt M16 LMG or simply as the Colt LMG (Light Machine Gun), t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heckler & Koch G11
The Heckler & Koch G11 is a non-production prototype assault rifle developed from the late 1960s–1980s by ''Gesellschaft für Hülsenlose Gewehrsysteme'' (GSHG) (German for "Association for Caseless Rifle Systems"), a conglomeration of companies headed by firearm manufacturer Heckler & Koch (mechanical engineering and weapon design), Dynamit Nobel (propellant composition and projectile design), and Hensoldt Wetzlar (target identification and optic systems). The rifle is noted for its use of caseless ammunition. It was primarily a project of West Germany, though it was of significance to the other NATO countries as well. In particular, versions of the G11 were included in the U.S. Advanced Combat Rifle program. In 1990, H&K finished the development of the G11, intended for the ''Bundeswehr'' and other NATO partners. Although the weapon was a technical success, it never entered full production due to the political changes of German reunification and lack of procurement contra ...

Steyr ACR
The Steyr ACR was a prototype flechette-firing assault rifle built for the US Army's Advanced Combat Rifle program of 1989/90. Although the Steyr design proved effective, as did most of the weapons submitted, the entire ACR program ended with none of the entrants achieving performance 100% better than the M16A2, the baseline for a successful ACR weapon. Design The Steyr ACR has some superficial resemblance to the Steyr AUG, although it is rounder and the barrel is covered for almost its entire length, as opposed to the AUG where much of the barrel was exposed. Like the AUG the ACR is a bullpup design with the 24-round magazine located quite close to the buttstock of the gun. The stock was "split" from the magazine forward to a location just below the sights to open for cleaning. An optical sight was included as a standard feature. The Steyr employed a unique system to cycle through ammunition: instead of driving rounds forward into the chamber and being held in place by a lockin ...

AAI ACR
The AAI ACR was a prototype flechette-firing assault rifle built for the US Army's Advanced Combat Rifle program of 1989/90. Although the AAI design proved effective, as did most of the weapons submitted, the entire ACR program ended with none of the entrants achieving performance 100% better than the M16A2, the baseline for a successful ACR weapon. Design Based on AAI's SFR/XM19 rifle developed as part of the SPIW program, the AAI ACR was externally one of the more conventional entrants to the ACR program. A closed bolt, gas operated, full stocked, magazine fed, conventionally laid out rifle. The 1990 ACR Program Summary report describes the operation system as: "…incorporate an 'entrapped gas' operating system. Gun gases enter a cylinder, drive a piston to power the system, and prevent any leakage of propellant gases and residues into the other mechanism parts." Other contemporary sources describe it as innovative, but how it differs from traditional Long or Short stroke pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tungsten
Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements barring carbon (which sublimes at normal pressure), melting at . It also has the highest boiling point, at . Its density is , comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many ...
