The XM8 was a project to replace the M4 with a modular weapon that would be easy to modify for different combat scenarios. However, the US Army didn't think that it was good enough, despite it's epic reliability compared to other weapons, and so as the funding from the US went, the project was axed by HK.

However, in some games (such as Bad Company 2) the XM8 has been featured as a general issue weapon to armies such as the Legionnaire's Merc. Army, and has also proved to be effective in multiplayer game modes. So a lot of people now like the XM8 and think the US army were wrong to say the weapon wasn't what they were looking for
