Overview[]
The HK XM8 is a German-American assault rifle system developed by Heckler & Koch and Alliant Technosystems. It was designed in the early 2000s as part of the OICW Project, and was presented to the United States Army as a possible replacement weapon. At the end of October 2005, the US Army cancelled the project, however the Malaysian Navy took interest in the weapon and it has been in service with them since 2010, where they operate modified versions of the weapon.
