The G36 is a 5.56×45mm assault rifle, designed in the early 1990s by Heckler & Koch in Germany as a replacement for the heavier 7.62mm G3 battle rifle. It was accepted into service with the Bundeswehr in 1997, replacing the G3. The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine.
The G36 is a selective-fire 5.56 mm assault rifle, firing from a closed rotary bolt. The G36 has a conventional layout and a modular component design. Common to all variants of the G36 family are: the receiver and buttstock assembly, bolt carrier group with bolt and the return mechanism and guide rod. The receiver contains the barrel, carry handle with integrated sights, trigger group with pistol grip, handguard and magazine socket.
The G36 employs a free-floating barrel (the barrel does not contact the handguard). The barrel is fastened to the receiver with a special nut, which can be removed with a wrench. The barrel is produced using a cold hammer forging process and features a chrome-lined bore with 6 right-hand grooves and a 1 in 178 mm (1:7 in) rifling twist rate. The barrel assembly consists of the gas block, a collar with a bayonet lug that is also used to launch rifle grenades and a slotted flash suppressorView Fullscreen

- G36V (V—Variante “variant”): Previously known as the G36E (E—Export), it is the export version of the standard G36. The G36V has all of the characteristics of the standard rifle with the exception of the sight setup and bayonet mount. It is fitted with a x1.5 or x3 sight and lacks the integrated reflector sight; the bayonet mount is a standard NATO type. This version was produced for Spain and Latvia.
- MG36 (MG—Maschinengewehr “machine gun”): Squad automatic weapon version of the G36 equipped with a heavier barrel for increased heat and cook-off resistance. The MG36 and MG36E are no longer offered by H&K.
- G36K (K—kurz “short”): carbine variant with a shorter barrel (fitted with an open-type flash suppressor) and a shorter forend, which includes a bottom rail that can be used to attach tactical accessories, such as a UTL flashlight from the USP pistol. The carbine’s barrel lacks the ability to launch rifle grenades and it will not support a bayonet. The weapon retained the ability to be used with the AG36 grenade launcher. G36Ks in service with German special forces are issued with a 100-round C-Mag drum. There are two variants of the G36K. The first and most commonly known has x3 scope/carry handle attached to the top, while the second is equipped with iron sights and a rail (no scope included).
- G36KV (formerly G36KE): export version of carbine variant, G36K with sights like G36V.
- G36C (C=”Compact”, commonly mistaken for “Commando”, a term trademarked by Colt Firearms for the CAR-15): This subcarbine model is a further development of the G36K. It has a shorter barrel than the G36K, and 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 the length of the gas piston operating rod. The handguard and stock were also shortened and the fixed carry handle (with optics) was replaced with a carrying handle with an integrated MIL-STD-1913 Picatinny rail. 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 a vertical grip. The G36C was developed and produced in January 2001.
- G36A2: This is an ordnance designation allocated to an upgraded variant of the G36 used by the German Army. The G36A2 is equipped with a quick-detachable Zeiss RSA reflex red dot sight mounted on a Picatinny rail that replaces the original red dot sight of the dual combat sighting system. The G36A2 upgrade kit also consists of the shorter G36C stock (Designed for better handling with use of body armor and load bearing equipment), new handguard made of aluminium (provides better heat resistance during long periods of firing) with an optional 4 Picatinny rails and a vertical foregrip with an integrated switch for operating an Oerlikon Contraves LLM01 laser light module
