The Heckler & Koch PSG1 (''Präzisionsschützengewehr'', German for "precision marksman rifle") is a semi-automatic designated marksman rifle designed and produced by the German company Heckler & Koch. Development This rifle is said to have been developed in response to the Munich massacre at the 1972 Summer Olympics. The West German police units at the time lacked the precision shooting capability to effectively neutralize the terrorists to prevent the hostages being killed. H&K was then commissioned to create a high-accuracy, large-magazine capacity, semi-automatic rifle for law enforcement and military use. Design details The PSG1 is mechanically based on the Heckler & Koch G3 battle rifle that employs a roller-delayed blowback operating system. Its shot-to-shot variation is expected to be better than 1 minute of angle (MOA) with match ammunition. This level of accuracy is only average compared to most modern bolt action sniper rifles, but is still exceptional for a semi-a ...

Heckler & Koch G3
The Heckler & Koch G3 () is a selective fire, select-fire battle rifle chambered in 7.62×51mm NATO developed in the 1950s by the German firearms manufacturer Heckler & Koch, in collaboration with the Spanish state-owned firearms manufacturer CETME. The G3 was the service rifle of the German ''Bundeswehr'' until it was replaced by the Heckler & Koch G36 in the 1990s, and was adopted into service with numerous other countries. The G3 has been exported to over 70 countries and manufactured under license in at least 15 countries. Over 7.8 million G3s have been produced. Its modular design was used for several other HK firearm models, including the Heckler & Koch HK21, HK21, Heckler & Koch MP5, MP5, Heckler & Koch HK33, HK33, Heckler & Koch PSG1, PSG1, and Heckler & Koch G41, G41. History The origin of the G3 can be traced back to the final years of World War II when Mauser engineers at the Light Weapon Development Group (''Abteilung 37'') at Oberndorf am Neckar designed the ''Mas ...

Heckler & Koch
Heckler & Koch GmbH (HK or H&K; ) is a German firearms manufacturer that produces handguns, rifles, submachine guns, and grenade launchers. The company is located in Oberndorf am Neckar, Baden-Württemberg and also has subsidiaries in the United Kingdom, France, and the United States. Heckler & Koch was founded in 1949 by former Mauser engineers Edmund Heckler, Theodor Koch, and Alex Seidel, who founded the company out of the shuttered Mauser factory in Oberndorf. The company initially produced machine tool and metal parts until 1956 when, in response to a contract for a new service rifle, HK developed the Heckler & Koch G3. The success of the G3 rifle prompted HK to transition to the defense industry. HK was owned by Royal Ordnance from 1991 to 2002, and is currently part of the Heckler & Koch Group, comprising Heckler & Koch GmbH, Heckler & Koch Defense, NSAF Ltd., and Heckler & Koch France SAS.

West German
West Germany was the common English name for the Federal Republic of Germany (FRG) from its formation on 23 May 1949 until its reunification with East Germany on 3 October 1990. It is sometimes known as the Bonn Republic after its capital city of Bonn, or as the Second German Republic. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from 12 states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France. At the onset of the Cold War, Europe was divided between the Western and Eastern blocs. Germany was divided into the two countries. Initially, West Germany claimed an exclusive mandate for all of Germany, representing itself as the sole democratically reorganised continuation of the 1871–1945 German Reich. Three southwestern ...

Free-floating Barrel
A free-floating barrel is a firearm design used in precision rifles, particularly match grade benchrest rifles, to accurize the weapon system. With conventional rifles, the gun barrel rests in contact with the fore-end of the gunstock, sometimes along the whole length. If the stock is wooden, environmental conditions or operational use may warp the wood, which may also cause the barrel to shift its alignment slightly over time, altering the projectile's external ballistics and thus the point of impact. Contact between the barrel and the stock affects the natural frequency of the barrel, which can reduce accuracy especially when the barrel gets hot with repeated firing. The effect of the stock on the barrel can cause the barrel to vibrate inconsistently from shot to shot, depending on the external forces acting upon the stock at the time of the shot. Such vibrations affect the bullet's trajectory, changing the point of impact. A free-floating barrel is one where the bar ...

Reticle
A reticle or reticule, also known as a graticule or crosshair, is a pattern of fine lines or markings built into the eyepiece of an optical device such as a telescopic sight, spotting scope, theodolite, optical microscope or the electronic visual display, screen of an oscilloscope, to provide frame of reference, measurement references during visual inspections. Today, engraved lines or embedded fibers may be replaced by a digital image superimposed on a screen or eyepiece. Both terms may be used to describe any set of patterns used for aiding visual measurements and calibrations, but in modern use ''reticle'' is most commonly used for weapon sight (device), sights, while ''graticule'' is more widely used for non-weapon measuring instruments such as oscilloscope#Graticule, oscilloscope display, astronomic telescopes, microscopes and microscope slide, slides, surveying instruments and other similar devices. There are many variations of reticle pattern; this article concerns its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telescopic Sight
A telescopic sight, commonly called a scope informally, is an optical sighting device based on a refracting telescope. It is equipped with some form of a referencing pattern – known as a ''reticle'' – mounted in a focally appropriate position in its optical system to provide an accurate point of aim. Telescopic sights are used with all types of systems that require magnification in addition to reliable visual aiming, as opposed to non-magnifying iron sights, reflector (reflex) sights, holographic sights or laser sights, and are most commonly found on long-barrel firearms, particularly rifles, usually via a scope mount. Similar devices are also found on other platforms such as artillery, tanks and even aircraft. The optical components may be combined with optoelectronics to add night vision or smart device features. History The first experiments directed to give shooters optical aiming aids go back to the early 17th century. For centuries, different optical ...

Iron Sights
Iron sights are a system of physical alignment markers used as a sighting device to assist the accurate aiming of ranged weapons such as firearms, airguns, crossbows, and bows, or less commonly as a primitive finder sight for optical telescopes. Iron sights, which are typically made of metal, are the earliest and simplest type of sighting device. Since iron sights neither magnify nor illuminate the target, they rely completely on the viewer's naked eye and the available light by which the target is visible. In this respect, iron sights are distinctly different from optical sight designs that employ optical manipulation or active illumination, such as telescopic sights, reflector (reflex) sights, holographic sights, and laser sights. Iron sights are typically composed of two components mounted perpendicularly above the weapon's bore axis: a 'rear sight' nearer (or 'proximal') to the shooter's eye, and a 'front sight' farther forward (or 'distal') near the muzzle.

M16 Rifle
The M16 (officially Rifle, Caliber 5.56 mm, M16) is a family of assault rifles adapted from the ArmaLite AR-15 rifle for the United States Armed Forces, United States military. The original M16 was a 5.56×45mm NATO, 5.56×45mm automatic rifle with a 20-round magazine. In 1964, the XM16E1 entered US military service as the M16 and in 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. The M16A1 incorporated numerous modifications including a bolt-assist ("forward-assist"), chrome-plated bore, protective reinforcement around the magazine release, and revised flash hider. In 1983, the United States Marine Corps, US Marine Corps adopted the M16A2 rifle, and the United States Army, 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 ha ...

Forward Assist
Forward assisting is the practice of moving the bolt or bolt carrier of a firearm fully forward ''in battery'' when the return spring has not done so (or there is a chance that it will not have done so) to prevent out-of-battery firing. It is only used on closed bolt only firearms. Some firearms have a dedicated device to allow forward assisting; on others, it is simply a procedure performed on reciprocating (i.e. attached to the bolt/bolt carrier) charging handles. As a device The forward assist is a button found on firearms with non-reciprocating (i.e. not attached to the bolt/bolt carrier) cocking handles, commonly on AR-15 rifle derivatives, such as the M16 rifle, and is usually located on the receiver near the bolt closure. It is a ratchet-like device that interfaces with the multiple serrations found on the side of the bolt carrier. The original AR15 and M16 designs lacked the "bolt forward assist" feature found on the later M16A1. When hit, it pushes the bolt carrie ...
