XM8

The XM8 was the U.S. military designation for a lightweight assault rifle system under development by the United States Army from the late 1990s to early 2000s. The rifle 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 OICW. (If you don't know what that is Google it.) OICW was developing a "smart" grenade launcher system with an underslung carbine rifle as a backup weapon. 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. The project was put on hold in April 2005, and was formally canceled on October 31, 2005. Such a sad day on Oct. 31 2005. In Concept this weapon comes with a built-in scope but you can attach your ACOG or your convenient 12x scope and make an automatic sniper rifle. It takes 5.56 mags which you find EVERYWHERE and can take anywhere from 30 round to 100 round mags.
