Barrett M107CQ Edit
A commercial development of the "new" M107, the M107CQ is specifically designed where the firepower of a .50 caliber rifle is required, but the bulk of the M82/M107 series prevents the weapon from being used. The M107CQ is 9" shorter in overall length (all in the barrel) and 5 pounds lighter than the M107. According to the manufacturer, the M107CQ is suitable for use in helicopters, force protection watercraft, tactical scout land vehicles, and as an urban soldier's combat multiplier for close quarters battles.
