Heckler & Koch G36
Produced by Heckler & Koch Santa Bárbara Sistemas Military Industries Corporation
The Heckler & Koch G36 (German: Gewehr 36) is an assault rifle designed in the early 1990s by German weapons manufacturer Heckler & Koch. It is chambered in 5.56×45mm NATO, and replaced the heavier G3 battle rifle chambered in 7.62×51mm. The G36 was accepted into service with the Bundeswehr in 1997. Since then, it has been a popular export, and has seen active service in military and police units in several countries, including Germany, Spain, and 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 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.
