The XM8 was designed by German small arms manufacturer Heckler & Koch (H&K) and shares design and engineering with their G36 rifle.
The XM8 design was originally part of the Objective Individual Combat Weapon program (OICW), which was developing a "smart" grenade launcher system with an underslung carbine rifle. The system was unable to meet performance and weight requirements and was eventually canceled. In the aftermath, the two portions of the OICW were separated, resulting in the XM8 and XM25 projects.
Although there were high hopes that the XM8 would become the United States Army's new standard infantry rifle, the project was put on hold in April 2005, and was formally canceled on October 31, 2005. However, the weapon is now in service with Royal Malaysian Navy special forces.
