From the G3A3 the barrel was free floated from the stock and had polygonal rifling . The barrel chamber is fluted with twelve flutes, which assists in

672-749: A basis for many other weapons, among them: the PSG1 and MSG90 precision rifles, the HK11 and HK21 family of light machine guns , a semi-automatic version known as the HK41 , a "sporterized" model called the SR9 (designed for the civilian market in countries where the HK91 would not qualify, primarily the US after the 1989 importation restrictions) and the MC51 carbine. The G3 rifle

756-602: A cartridge outside of the NATO specification, the Germans asked CETME to develop a 7.62×51mm version of the rifle. The resulting CETME Model A was chambered for the 7.62×51mm CETME cartridge which was identical in chamber dimensions but had a reduced-power load compared to the 7.62×51mm NATO round. Further development of the rifle with input from H&K produced the CETME Model B which received several modifications, including

840-514: A dust cover. The rifle can be fitted with a 40mm AG36 (AG— Anbau-Granatwerfer ) under-barrel grenade launcher , which loads via a side-tilting break action . Standard equipment supplied with the G36 includes: spare magazines, a cleaning and maintenance kit, sling, speedloader and sometimes modified AKM type II blade bayonets (many of which are left over in Germany from stocks of the former National People's Army ). Introduced in 1996,

924-451: A fully loaded magazine weighs 483 g (17.0 oz). While STANAG magazines are not normally compatible with the G36, adapters and modifications exist that enable cross-compatibility. Certain types of Beta C-Mags , which hold 100 rounds, can also be used with the stock G36, and are employed by the MG36 variant. The G36 features a folding stock, which can shorten the overall length of

1008-599: A further 17,000 rifles. Deliveries were first made to the Bundeswehr ' s NATO Quick Reaction Force during quarter four of 1997. The G36's production line was started in early 1996. In July 1998, it was announced that the G36 had been selected as the service rifle for the Spanish Armed Forces , replacing the Spanish-designed 5.56mm CETME Model L and LC rifles. Deliveries started at

1092-575: A lightweight folding bipod, a stamped sheet steel handguard, a wooden buttstock (in fixed stock models) or a telescopic metal stock. Before delivery to the Bundeswehr, each G3 went through functional checks, zeroing the sight line ( Anschießen ) and a shooting test at the factory. In the process, five shots were fired at a target at 100 metres (109 yd) with particularly accurate sighting-in ammunition. The 5-shot group could not exceed 120 mm (4.7 in) (1.2 mil /4.13 MOA ) diameter. The weapon

Presidential Security Group Guardia Civil Heckler %26 Koch G3 The Heckler & Koch G3 ( German : Gewehr 3 ) is a 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

1260-425: A proper and safe functioning parameters bandwidth Heckler & Koch offer a variety of locking pieces with different mass and shoulder angles. The angles are critical and determine the unlock timing and pressure curve progression as the locking pieces act in unison with the bolt head carrier. The G3 is a modular weapon system. Its butt-stock, fore-stock and pistol-grip/fire-control assembly may be changed at will in

1344-496: A relatively high trigger pull of 50–55  N (11.2–12.4  lb f ) due to a drop safety requirement. An interchangeable set-trigger pack assembly featuring a trigger stop and less trigger pull is available for the G3SG/1 and other sniping orientated variants. The original G3 and G3A1 rifle variants had a relatively low iron sight line that consisted of a Klappvisier, an "L-type" flip up rear sight and hooded front post. From

1428-454: A relatively inexpensive way to extend the service life of the G36 in the Bundeswehr pending the outcome of legal procedures regarding a new system assault rifle tender for the Bundeswehr . The TommyBuilt Tactical T36 is an American-made clone receiver based on the G36, which was started in 2007 by Tom Bostic based on converting a SL8 to a G36. In February 2021, the BATF classified it as

1512-484: A single telescopic sight with 1.5× magnification and a fixed 300 m (328 yd) reticle. All rifles are adapted to use the Hensoldt NSA 80 third-generation night sight , which clamps into the G36 carry handle adaptor in front of the optical sight housing and mates with the rifle's standard optical sight. The sighting bridge also functions as a carrying handle and features auxiliary open sights moulded on top of

1596-1011: A trigger rated at 20  N (4.5  lb f ). In November 2013, Heckler & Koch applied for permission from the German Government to sell a new civilian-legal version of the G36. Known as the HK243 in Europe and the HK293 in America, it is more similar to the G36 assault rifle than previous civilian models. The main difference is the bolt is redesigned not to allow a conversion to fully automatic fire. It has quad picatinny rails and accepts STANAG magazines. Four different barrel lengths from 230 mm (9.1 in) to 480 mm (19 in) and four stock models (short fixed, long fixed and two adjustable) will be offered. In November 2020, semi-automatic only G36 rifles became available for sale on

1680-639: A variety of configurations (listed below). Simple push-pins hold the components in place and removing them will allow the user to remove and replace parts rapidly. The weapon made extensive use of cost-saving pressed and stamped steel components rather than machined parts and spot welding to connect parts. The stamped sheet metal cocking handle tube and receiver are large exposed parts that are prone to deformation from hard impact as they were designed to be relatively thin to save weight. If dented severely or deep enough during field service, reliability problems due to internal parts movement impairments can occur that put

1764-673: A vertical foregrip with an integrated switch for the LLM01 laser light module . Throughout its service life, it has received further modernisation upgrades, designated as the G36A3 and G36A4 . Some G36A1 rifles were given the same modernisation upgrades as the G36A3 while reusing the original, cheaper A1 receiver. These variants are known as the G36A1.1 . Introduced in 1997, the G36K (K— kurz "short")

The resultant weapon, Gerät 06H (the "H" suffix is an abbreviation for halbverriegelt - "half-locked") was assigned the designation StG 45(M) ( Sturmgewehr 45(M) , assault rifle 45) but was not produced in significant numbers and

2772-540: The Ministry of Defence attempted to sue Heckler & Koch, saying they were legally obligated to repair the subpar G36 rifles. Because the Bundeswehr did not make its specifications for the weapon clear enough in the beginning of the procurement process, the District Court of Koblenz rejected claims from the Bundeswehr procurement office, and ruled that Heckler & Koch did not have to pay damages on

2856-435: The barrel , carry handle with integrated sights , trigger group with pistol grip , handguard and magazine socket. The G36 employs a free-floating barrel, meaning the barrel does not make contact with the handguard. The barrel is fastened to the receiver with a special nut, which can be removed with a wrench. The barrel is forged using a cold hammer process. It features a chrome-lined bore with 6 right-hand grooves and

The weapon can be fitted with an optional four-position safety/fire selector group illustrated with pictograms with an ambidextrous selector lever. The additional, fourth selector setting enables a three-round burst mode of fire. The rifle has

3024-558: The 167,000 rifles still in use out of more than 176,000 G36 rifles Germany had originally purchased. The Bundeswehr began the System Sturmgewehr Bundeswehr (Bundeswehr Assault Rifle System) effort to replace the G36 in 2017. Initially, C.G. Haenel won the competition in September 2020 offering their Haenel MK 556 . However, German authorities cancelled the contract the next month amid allegations that

3108-511: The Austrian competition (the Steyr AUG system). The final version of the G36 was completed in 1995, and production began in 1996. The G36C was first adopted as the standard-issue rifle of US special forces unit TF23. The HK50 rifle was selected for service and an initial order was placed for 33,000 rifles under the Bundeswehr designation Gewehr G36. The order included an option for

3192-750: The Bundesgrenzschutz canceled their planned procurement of the CETME rifles, adopting the Belgian-made FN FAL as the Gewehr 1 (G1) instead. However, the newly formed West German Army ( Bundeswehr ) now showed interest and soon purchased a number of CETME rifles (7.62×51mm NATO chambering) for further testing. The CETME, known as the Automatisches Gewehr G3 according to German nomenclature, competed successfully against

3276-539: The Fraunhofer Ernst Mach Institut and Wehrtechnische Dienststelle 91 on 19 April 2015. According to their 372-page report, the observed hit rate of the predominantly plastic weapon with the unsupported free-floating barrel drops down to a mere 7% at 100 metres when the temperature increases by 30 °C (86 °F) or more, whereas the Bundeswehr required a hit rate of 90% at that distance. On 22 April 2015, von der Leyen announced that

3360-673: The G1 had previously fallen through over FN's refusal to grant such a license. In the case of the G3, the Dutch firm Nederlandse Wapen en Munitiefabriek (NWM) held production and sales rights to the CETME design outside of Spain. To acquire production rights, the West German government offered NWM contracts to supply the German Air Force (Luftwaffe) with 20mm ammunition. Production of the G3

3444-655: 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 Maschinenkarabiner Gerät 06 (MKb Gerät 06, "machine carbine device 06") prototype assault rifle chambered for the intermediate 7.92×33mm Kurz cartridge, first with the Gerät 06 model using a roller-locked short recoil mechanism originally adapted from

3612-419: The G36 would be phased out of the German army due to these concerns and stated that "The Heckler & Koch G36 has no future in the German army in its current state of construction." Von der Leyen considered the weapon to be useless and stated that the German military would stop using an assault rifle that could not shoot straight when temperatures increased or the rifle heated up during a firefight. In 2016,

3696-645: The G36. The weapons put forth were the Heckler & Koch HK416 , Heckler & Koch HK433 , and the Haenel MK 556 . The G95A1 and G95KA1, both variants of the HK416, were selected in 2022. In the 1970s, arms manufacturers in Germany began work on a successor for the G3 rifle, resulting in the creation of the 4.73mm G11 assault rifle (developed jointly by a group of companies led by Heckler & Koch) that used caseless ammunition (designed by Dynamit Nobel ). This weapon

3780-1091: The G3A2 variant the firearm is equipped with a relatively low iron sight line that consists of a Drehvisier a rotary rear drum and hooded front post. The rear sight is mechanically adjustable for both windage and elevation with the help of tools. This deliberately prevents non-armorers to (re)zero the iron sight line. The rotary drum features an open V-notch (numbered 1) for rapid target acquisition, close range, low light and impaired visibility use and three apertures (numbered 2, 3 and 4) used for: 200–400 metres (219–437 yd) in 100 metres (109 yd) increments for more precise aiming. The 1 V-notch and 2 or 200 metres (219 yd) aperture settings have an identical point of aim. The V-notch and apertures are calibrated for US M80 / German DM111 series or other equivalent 9.5 grams (147 gr) 7.62×51mm NATO ball ammunition. The receiver housing has recesses that work with STANAG claw mounts/HK clamp adapters used to mount day or night aiming optics. The rifled barrel – four right-hand grooves with

3864-558: 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 HK21 , MP5 , HK33 , PSG1 , and G41 . The origin of

3948-675: The MK 556 infringed on Heckler and Koch patents, and the G95A1 (known as the HK416 A8 during field testing) was selected in early 2021. Haenel sued to attempt to reverse the decision, but a German court dismissed the lawsuit in June 2022. In December 2022, the Bundestag approved initial funding to begin procuring the rifles. The Bundeswehr expected to purchase 118,718 rifles, designated G95A1 (with

4032-620: The Swiss SIG SG 510 (G2) and the American AR-10 (G4) to replace the previously favored G1 rifle. In 1956 the Bundeswehr started extended troop trials with 400 CETME rifles. Heckler & Koch made a number of changes to the CETME rifles. In January 1959, the Bundeswehr officially adopted the technically improved CETME proposal. The West German government wanted the G3 rifle to be produced under license in Germany; purchase of

4116-739: The United Kingdom ( Royal Ordnance ). The Bundeswehr was working on improving their G3 rifles in the 1990s with a brass deflector that deflects spent cartridge cases down and frontwards from the operator and a new polymer pistol-grip/fire-control assembly module that allows better ambidextrous operation of the safety lever when they had their G3 rifles replaced for the Heckler & Koch G36 . Currently (2018) hundreds of thousands of G3A3A1, G3A4A1 and G3KA4A1 modernized variants rifles are maintained by Bundeswehr personnel and kept in reserve or are available in military base small arms storages. The Iranian version remains in production as of 2024. The G3

4200-408: The United Kingdom. The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine . In 2012, the G36 was found to suffer from significant accuracy issues due to thermal expansion of the barrel, prompting a search for a replacement. In 2017, the Bundeswehr launched the System Sturmgewehr Bundeswehr , a program designed to field a replacement for

4284-454: The West German government ceded ownership of G3 production and sales rights exclusively to Heckler & Koch. After obtaining these rights, Heckler & Koch initially had to pay the government 4 Deutsche Marks per rifle, despite having been awarded the contract by the German government. Initial production G3 rifles differed substantially from more recent models; early rifles featured closed-type mechanical flip-up sights (with two apertures),

In 1958, this rifle was accepted into service with the Spanish Army as the Modelo 58 , using the 7.62×51mm CETME round. In 1956,

4452-635: The adoption of these new weapons for financial reasons. In 1950, Vorgrimler moved to Spain where he created the LV-50 rifle chambered for the Kurz cartridge and later, the proprietary 7.92×40mm CETME M53 round. At this point, the rifle was renamed the Modelo 2 . The Modelo 2 drew the attention of the West German Bundesgrenzschutz (Border Guards), who sought to re-equip the newly formed national defense forces. Not willing to accept

4536-497: The ammunition confirmed this, although experts disagreed, and also said the accuracy problems were already known to the defence ministry by 2010. On 22 June 2014, it was reported that Germany's defense ministry had temporarily halted new orders worth €34 million ($ 45 million) over accuracy concerns for the rifle. The Bundeswehr consulted the Fraunhofer Institute for High-Speed Dynamics (Ernst Mach Institut) and

4620-406: The barrel extension recesses. The bolt features an anti-bounce mechanism that prevents the bolt from bouncing off the barrel's breech surface. The "bolt head locking lever" is a spring-loaded claw mounted on the bolt carrier that grabs the bolt head as the bolt carrier group goes into battery. The lever essentially ratchets into place with friction, providing enough resistance to being re-opened that

4704-418: The bolt carrier does not rebound. The spring-powered claw extractor is also contained inside the bolt while the lever ejector is located inside the trigger housing (actuated by the recoiling bolt). The chamber has longitudinal gas relief flutes cut in the chamber wall to ease the cartridge case's extraction upon firing. These flutes allow propellant gas to flow between the case and chamber wall, equalizing

The L17A1 and L123A2 UGL (Underslung Grenade Launcher) are the under-barrel 40 mm grenade launchers used by the British Army in conjunction with the L85A2 rifle (L123A2 UGL), and in small numbers with the L119A1 carbine used by United Kingdom Special Forces and the Pathfinder Platoon (L17A1 UGL). It

5628-469: The length of the gas piston operating rod. The handguard and stock were also shortened, and it includes the carrying handle from the G36KA4 The dual optical sight found on the standard G36 and G36K models was replaced with a set of rail-mounted detachable iron sights that consist of a semi-shrouded front post and a flip-up rear sight with two apertures of different diameter. The short handguard has four accessory attachment points, one of which could be used for

5712-436: The operating cycle. Based on the geometric relationship arising from the angles of the roller contact surfaces of the locking piece and the barrel extension recesses, the recoil of the bolt head is delayed by a ratio of 4:1 for the 7.62×51mm NATO chambering. Thus during the same period of time, the bolt head carrier moves 4 times faster than the bolt head. This ratio is continued until the locking rollers have been withdrawn from

5796-404: The piston instead of pushing directly on the bolt. The G36's bolt is operated by a cam that guides the bolt carrier by its respective cut-out. Then, when fully pushed forward, 7 radial locking lugs fully enclose the chamber. The design includes several features that are commonplace in modern military firearms. The bolt locks back after the last round is spent, although this can be deactivated using

5880-508: The pressure between the inner and outer surfaces of the front of the cartridge case. The intentional propellant gas ingress at the gas relief flutes significantly reduces case friction against the chamber wall, making extraction more reliable by preventing the cartridge case from sticking and tearing. The reliable functioning of roller-delayed blowback mechanisms is limited by specific ammunition and arm parameters like bullet weight, propellant charge, barrel length and amount of wear. For obtaining

5964-404: The rifle include: a detachable bipod (not included with rifles that have a perforated plastic handguard), sling, cleaning kit and a speed-loading device. Several types of bayonet are available for the G3, but with few exceptions they require an adapter to be inserted into the end of the cocking tube. The most common type features a 6 3 ⁄ 4  inch spear-point blade nearly identical with

6048-454: The rifle out of action and can not be field solved by the user. To determine and correct such situations armorers are trained to employ specially designed "GO" and symmetry gauges and straightening mandrels to fairly quickly repair such problems. The rifle is hammer fired and has a trigger mechanism with a 3-position fire selector switch that is also the manual safety toggle that secures the weapon from accidentally discharging (fire selector in

6132-425: The straight-pull, bolt-action R8 , which are offered to the civilian sport shooting markets, both are loosely based on the G36. The SL8 is substantially different from the G36, it has a modified receiver and a thumbhole stock with a cheek rest, which is integral with the trigger group. The SL8 has a heavy profile, extended, 510 mm (20.1 in) barrel that does not have a flash hider or bayonet lug. The rifle uses

6216-643: The unification of East and West Germany , and Heckler & Koch's 1991 acquisition by British Aerospace's Royal Ordnance division (known today as BAE Systems ). Increasing demand for a modern service rifle chambered in the NATO -standard 5.56mm cartridge led Heckler & Koch to offer the German armed forces the G41 rifle, which, too, was rejected. Design work was initiated on a completely novel, modern 5.56mm assault rifle; it would later be designated Project 50 or HK50 . During testing, prototypes were rated higher than

6300-468: The use of longer rounds when necessary, e.g. baton or flare rounds. When open, the breech is on the left. For installation, the rifle's existing barrel handguard is removed and replaced by the AG36. The weapon has a trigger group with a manual safety lever and a pistol grip for ease of handling. Aiming is accomplished using standard ladder sights, which are located on the left side of the launcher body and folded down when not in use. Due to its modular design,

6384-574: The war ended before the first production rifles were completed. The German technicians involved in developing the StG 45(M) were taken to work in France at Centre d'Etudes et d'Armement de Mulhouse (CEAM). The StG 45(M) mechanism was modified by Ludwig Vorgrimler and Theodor Löffler at the Mulhouse facility between 1946 and 1949. Three versions were made, chambered in .30 Carbine , 7.92×33mm Kurz , and

6468-410: The weapon for close-quarters combat . The stock also incorporates holes in which assembly pins can be stored during weapon cleaning and maintenance. The G36 employs a number of lightweight, corrosion-resistant synthetic materials in its design. The receiver housing, stock, trigger group (including the fire control selector and firing mechanism), magazine well, handguard and carry handle are all made of

6552-545: The weapon to cool between periods of rapid shooting. In February 2014, the German Federal Ministry of Defence announced that the overheating deficiencies of the G36 were not a result of weapon design, but of the ammunition. A report by the Bundeswehr on 21 February 2014 revealed that the issues were not the fault of the rifle, but that one manufacturer of ammunition was making bullets with copper-plated jackets that were too thin. The manufacturer of

6636-466: Was also replaced with an IdZ adjustable stock for better handling while using body armour. Introduced in 2001, the G36C (C="Compact") is a compact variant and a further development of the G36K. It has a shorter barrel than the G36K and either a four-prong open-type flash hider or a birdcage type flash hider. The extremely short barrel forced designers to move the gas block closer to the muzzle end and reduce

6720-590: Was first produced for the Spanish and Latvian National Armed Forces . The G36A2 is an upgraded variant of the G36 also in service with in the German Army. It is equipped with a quick-release Zeiss RSA reflex red dot sight mounted on a Picatinny rail , replacing the original red dot sight. The G36A2 includes the shorter G36C stock, a new handguard made of aluminium (permitting better heat dissipation during sustained fire), an optional four Picatinny rails, and

6804-497: Was intended to replace the G3, therefore further development of Heckler & Koch's series of firearms chambered for the 5.56×45mm NATO cartridge had been halted. Heckler & Koch, having no incentive to pursue a new 5.56mm weapon system, was content with the export-oriented HK33 and G41 rifles. However, the G11 program came to an abrupt end when the Bundeswehr cancelled its procurement due to defence budget cuts resulting from

6888-522: Was modernized during its service life (among other minor modifications it received new sights, a different flash suppressor , and a synthetic handguard and shoulder stock), resulting in the most recent production models, the G3A3 (with a fixed polymer stock) and the G3A4 (telescoping metal stock). The rifle proved successful in the export market, being adopted by the armed forces of over 40 countries. Of that figure, 18 countries undertook domestic production of

6972-610: Was produced at MIC's factory on 30 June 2009. However, some components of their own G36s are supplied by Heckler & Koch. In April 2012, reports surfaced that G36 rifles used in Afghanistan would overheat during prolonged firefights after several hundred rounds were fired. Overheating affected the accuracy of the G36, making it difficult to hit targets past 100 metres, ineffective past 200 metres, and incapable of effective fire past 300 metres. The G36 has been called unsuitable for long battles. Operational commanders advised allowing

7056-417: Was then assigned to Rheinmetall and Heckler & Koch. The latter company already had ties to CETME, and had worked to further optimize the CETME rifle for use with the full-power 7.62×51mm NATO cartridge (as opposed to the downgraded CETME variant). In 1969, Rheinmetall gave up production rights to the G3 in exchange for Heckler & Koch's promise not to bid on MG 3 machine gun production. Later in 1977,
