Heckler & Koch GmbH (HK) ((:ˈhɛklɐʔʊntˈkɔx)) is a German defense manufacturing company that manufactures handguns, military rifles, submachine guns, and grenade launchers. The company is located in Oberndorf in the state of Baden-Württemberg, and also has subsidiaries in the United Kingdom, France and the United States. The Heckler & Koch Group comprises Heckler & Koch GmbH, Heckler & Koch Defense, NSAF Ltd., and Heckler & Koch France SAS. The company motto is "''Keine Kompromisse!''" (No Compromises!).〔 HK provides firearms for many military and paramilitary units, like the Special Air Service, U.S. Navy SEALs, Delta Force, FBI HRT, the German KSK and GSG 9 and many other counter-terrorist and hostage rescue teams. Their products include the MP5 SMG, the G3 battle rifle, the HK33, G36, HK416 assault rifles, the Heckler & Koch HK21 general-purpose machine gun, the MP7 PDW, the UMP SMG, the USP series of handguns, and the high-precision PSG1 sniper rifle. All firearms made by HK are named by a prefix and the official designation, with suffixes used for variants. HK has a history of innovation in firearms, such as the use of polymers in weapon designs and the use of an integral rail for flashlights on handguns. HK also developed modern polygonal rifling, noted for its high accuracy, increased muzzle velocity and barrel life. Not all of its technologically ambitious designs have translated into commercially successful products (for instance, the advanced but now abandoned G11 military rifle, which fired caseless high-velocity ammunition). In its extensive product range, HK has used the following operating systems for small arms: blowback operation, short-recoil, roller-delayed blowback, gas-delayed blowback, and gas operation (via Short-stroke piston). ==History== With the fall of Germany at the end of World War II, Oberndorf came under French control, and the entire Waffenfabrik Mauser AG factory was dismantled by French occupying forces. All records in the factory were destroyed on orders of the local US Army commander. In 1948, three former Mauser engineers, Edmund Heckler, Theodor Koch, and Alex Seidel saved what they could from the factory and what they salvaged was used to start a machine tool plant in the vacant factory that became known as the Engineering Office Heckler & Co. On December 28, 1949, the Engineering Office Heckler & Co. changed its name and was registered officially as Heckler & Koch GmbH. Initially the new company manufactured machine tools, bicycle and sewing machine parts, gauges and other precision parts. In 1956, Heckler & Koch responded to the West German Government's tender for a new infantry rifle for the Bundeswehr (German Federal Army) with the proposal of the G3 battle rifle, which was based on the Spanish CETME rifle.〔〔 The German Government awarded Heckler & Koch this tender and by 1959, declared the G3 as the standard rifle of the Bundeswehr. In 1961, Heckler & Koch developed the 7.62×51mm HK21 general-purpose machine gun, based on the G3 battle rifle. In 1966, Heckler & Koch introduced the HK54 machine pistol, which eventually launched in 1969 as the MP5 machine pistol. Two years later, the company introduced the 5.56×45mm HK33 assault rifle, which is a smaller version of the G3 battle rifle chambered in 5.56mm NATO. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Heckler & Koch」の詳細全文を読む スポンサード リンク
