Heckler & Koch G36

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 7.62×51mm G3 battle rifle.[2] It was accepted into service with the Bundeswehr in 1997, replacing the G3.[3] Since then, it has also been a popular export, and the G36 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.[2]

In 2012, the G36 was found to suffer from severe accuracy problems when the weapon overheated, which prompted the search for a replacement.[4] In 2017, the Bundeswehr launched the System Sturmgewehr Bundeswehr, a program to find a replacement for the G36. The weapons put forth were the Heckler & Koch HK416, Heckler & Koch HK433, and the Haenel MK 556. Due to legal issues surrounding claims of Haenel engaging in patent infringement, the program has been put on hold, and the new replacement the HK416A8 was selected to become the new service rifle starting 2022.
