The Heckler & Koch G36 (Gewehr 36) is a 5.56×45mm assault rifle, designed in the early 1990s by German company Heckler & Koch 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 a 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 suppressor.
The weapon can be stripped and reassembled without tools through a system of cross-pins similar to that used on earlier HK designs. For cleaning purposes, the G36 dismantles into the following groups: receiver housing, return mechanism, bolt carrier group, and trigger group.
