Heckler & Koch G36

History Development

Work on a successor for the venerable G3 rifle had been ongoing in Germany since the second half of the 1970s. These efforts resulted in the innovative 4.73mm G11 assault rifle (developed jointly by a group of companies led by H&K), that used caseless ammunition (designed by the Dynamit Nobel company). It had been predicted that this weapon would eventually replace the G3, therefore further development of H&K's series of firearms chambered for the 5.56x45mm NATO cartridge had been halted. Heckler & Koch had no incentive to pursue a new 5.56mm weapon system, content with the export-oriented HK33 and G41rifles. However, the G11 program came to an abrupt end when the Bundeswehr canceled its procurement due to defense budget cuts after the unification of East and West Germany and H&K was acquired in 1991 by British Aerospace's Royal Ordnance division (known today as BAE Systems).

Increasing interest in Germany for a modern service rifle chambered for the NATO-standard 5.56mm cartridge led H&K to offer the German armed forces the G41 rifle, which, too, was rejected. Design work was then initiated from the ground up on a modern 5.56mm assault rifle designated "Project 50" or HK50.[2] The prototype was then trialed, where it was rated higher than the rival Austrian Steyr AUG system.[2]
[edit]Production

The HK50 rifle was selected for service and an initial order was placed for 33,000 rifles under the Bundeswehr designationGewehr G36. The order also involved an option for a further 17,000 rifles. Deliveries were first made to the Bundeswehr's NATOQuick Reaction Force during the third quarter of 1997.

In July 1998, it was announced that the G36 had been selected as the standard rifle for the Spanish Armed Forces, replacing the 5.56mm CETME Model L and LC rifles.[3] Deliveries first took place at the end of 1999. These rifles are manufactured inSpain under license by General Dynamics Santa Bárbara Sistemas at the FACOR (Fábrica de Armas de la Coruña) facility, inA Coruña, Galicia.


In addition, the rifle has been licensed for local production in Saudi Arabia.

Features


G36 Carbine with two magazine held together jungle style.

A standard German Bundeswehr G36 with bipod and a Beta C-Mag drum magazine

[edit]Fire selector

The fire and safety selector is ambidextrous and has controls on both sides of the receiver; the selector settings are described with letters: “S” – safe ("Sicher"), “E” – semi-automatic fire ("Einzelfeuer") and “F” – continuous fire ("Feuerstoß").[2] The weapon safety disables the trigger when engaged. HK also offers several other trigger options, including the so-called “Navy” trigger group, with settings analogous to the standard trigger, but the selector positions have been illustrated with pictograms. A semi-automatic only trigger unit (lacks the “F” setting) is also available. An integrated, manual safety mechanism prevents accidental firing (this is an improved trigger group from the G3 rifle).

[edit]Magazine

The G36 feeds from proprietary 30-round curved magazines very similar to those of the Swiss SIG 550 with cartridges loaded in a staggered pattern. The magazines are molded from a high-strength translucent polymer and can be clipped together using built-in coupling studs into 2 or 3-magazine packs allowing up to five magazines to be carried side-by-side on the rifle ready for rapid magazine changes; Jungle style. The magazines are not compatible with NATO-standard STANAG magazines, as introduced in the M16. However, G36 can use a magazine adaptator that will accept STANAG magazines.[5] The G36 can also use Beta C-Mag drum magazines (produced by Beta Company) that have a 100-round cartridge capacity and are intended to be used primarily with the MG36 light support weapon.

[edit]Stock

The MG36 variant is equipped with a side-folding skeletonized stock and a detachable folding bipod, which folds into recesses in the handguard. The G36 can be fired with the stock collapsed.[2] The underside of the butt-stock has holes into which assembly pins can be placed during weapon cleaning and maintenance.

[edit]Material

The G36 employs a large number of lightweight, corrosion-resistant synthetic materials in its design; the receiver housing, stock, trigger group (including the fire control selector and firing mechanism parts), magazine well, handguard and carry handle are all made of a carbon fiber-reinforced polyamide. The receiver has an integrated steel barrel trunnion (with locking recesses) and the reciprocating parts move on steel rails molded into the receiver (this feature was issued a US patent, number 5513461, authored by Helmut Weldle).

[edit]Sights

The standard German Army versions of the G36 are equipped with a ZF 3x4° dual optical sight that combines a 3x magnified telescopic sight (with the main reticule designed for firing at 200 m and bullet drop compensation markings for: 200, 400, 600 and 800 m crosshairs and a range-finding scale) and an unmagnified reflex sight (calibrated for firing at 200 m) mounted on top of the telescopic sight.[2] The reflex sight is illuminated by ambient light during the day and uses battery powered illumination for use at night. Electric illumination is activated automatically by a built in photo sensor and can be manually activated to boost the brightness of the reticle in daytime low contrast situations.[6]
The export versions have a single telescopic sight with a 1.5x magnification and an aiming reticule fixed at 300 m. All rifles are adapted to use the Hensoldt NSA 80 third-generation night sight, which clamps into the G36 carry handle adapter in front of the optical sight housing and mates with the rifle's standard optical sight.[7] The sighting bridge also functions as a carrying handle and features auxiliary open sights molded on top of the handle that consist of a forward blade and rear notch, but these can only be used with the reflex sight removed, as in the G36V. The optical sight system is produced by Hensoldt AG (a subsidiary of Carl Zeiss AG).
