XM8 image - moraman

The XM8 was one of America's best designed weapons since probably the M1 Garand. the XM8 fires the 5.56mm NATO, so there would be no need to change the ammo used in the US military. It was made so there could be many guns in one gun, including an assault rifle, a squad support weapon, a CQC variant, and even a marksman version. It was sadly denied entry into the Us military as Congress felt that the US military didn't need a new gun.
