allegations 3 hk abbreviations 4 see also 5 references 6 external links history edit 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 french 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. 3 4 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 . 5 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 . 3 4 the german government awarded heckler & koch this tender and by 1959 declared the g3 as the standard rifle of the bundeswehr . 6 7 in 1961 heckler & koch developed the 7.62 51mm hk21 general purpose machine gun based on the g3 battle rifle . 8 in 1966 heckler & koch introduced the hk54 machine pistol which eventually launched in 1969 as the mp5 machine pistol . 9 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 5.56 mm nato . 10 11 diversification edit in 1974 heckler & koch diversified into the following two business areas hk defense and law enforcement technology and hk hunting and sports firearms . since then hk has designed and manufactured more than one hundred different types of firearms and devices for the world s military and law enforcement organizations as well as sportsmen and hunters . 12 in 1990 heckler & koch finalised over two decades of development with their revolutionary case less weapon system and produces prototypes of the hk g11 . in addition the company produced prototypes of the hk g41 military rifle intended for the bundeswehr . due to the international political climate at that time east and west germany uniting and defense budget cuts the company was unable to secure funded contracts from the german government to support production of either weapon system and this resulted in the company becoming financially vulnerable . in the following year the heckler & koch company was sold to the british aerospace s royal ordnance division . 1 during 1994 and 1995 the german government awarded heckler & koch with contracts for producing an updated standard assault rifle and updated standard sidearm for the bundeswehr . as a result heckler & koch developed and produced the project hk50 a lightweight carbon fiber reinforced polymer assault rifle which became the hk g36 assault rifle . in addition heckler & koch produced the hk p8 derived as a variant based upon its universale selbstladepistole usp series of handguns which had been in production since 1989 . the p8 was adopted as the standard issue handgun for the bundeswehr in 1994 and the g36 was adopted in 1995 . 13 as the result of a 1999 merger between british aerospace and marconi electronic systems heckler & koch was then owned by bae systems and was contracted to refurbish the sa80 rifle for the british army . 14 this contract entailed a modification programme to the sa80 series of rifles to address a number of reliability issues with the sa80 . three years later in 2002 bae systems restructured and sold heckler & koch to a group of private investors who created the german group holding company hk beteiligungs gmbh . in 2003 the hk beteiligungs gmbh group s business organization restructured as heckler & koch jagd und sportwaffen gmbh hkjs and its business was separated into the following two business areas similar to the 1974 business mission areas defense and law enforcement and sporting firearms . in 2004 heckler & koch was awarded a major handgun contract for the dhs worth a potential 26.2 million for up to 65 000 handguns . 15 this contract ranks as the single largest handgun procurement contract in us law enforcement history . 16 heckler & koch facility in oberndorf am neckar . hk was contracted by the united states army to produce the kinetic energy subsystem 17 see kinetic projectiles or kinetic energy penetrator of the objective individual combat weapon a planned replacement for the m16 m203 grenade launcher combination . the oicw was designed to fire 5.56 mm bullets and 25 mm grenades . the kinetic energy component was also developed separately as the xm8 though both the oicw and xm8 are now indefinitely suspended . heckler & koch developed a colt m4 variant marketed as the hk416 . 18 hk replaced the direct impingement system used by the stoner design on the original m16 platform with a short stroke piston operating system . at this date there is no indication that the rifle will be adopted by the united states armed forces ; other than use in the marine corps as the iar or m27 . however the elite delta force and other special operations units have fielded the hk416 in combat 19 and oklahoma senator tom coburn has called for a free and open competition to determine whether the army should buy the hk416 or continue to purchase more m4 carbines . 20 incoming secretary of the army pete geren agreed in july 2007 to hold a dust chamber test pitting the m4 against hk s hk416 and xm8 as well as the rival fabrique nationale s sof combat assault rifle scar design . coburn had threatened to stop geren s senate confirmation if he did not agree to the test . 21 the hk xm8 and fn scar had the fewest failures in the test closely followed by the hk416 while the m4 had by far the most . 22 in 2007 the norwegian army became the first to field the hk416 as a standard issue rifle . 23 hk sells its pistols in the united states to both law enforcement and civilian markets . the company has locations in virginia new hampshire and georgia . trafficking allegations edit hk has been accused of shipping small arms to conflict regions such as bosnia 24 and nepal 25 and has licensed its weapons for production by governments with poor human rights records such as sudan thailand and burma . 26 it has been argued that the company effectively evaded eu export restrictions when these licensees sold hk weapons to conflict zones including indonesia 27 sri lanka 28 and sierra leone . 25 according to the stuttgarter nachrichten papers 31.8.11 as well as the state broadcaster ard a large stockpile of g36 assault rifles fell into rebel hands during the attack on colonel qaddafi s compound in tripoli in august 2011 reporting that pictures proved the rifles carried the company s trademark . it was
