Heckler & Koch's M320 can either serve its purpose as a powerful grenade launcher or bring double the pain by attaching itself onto an M4 Carbine or M16 assault rifle. It fires all NATO grenades (high-explosive, illuminating, and smoke), as well as less-lethal rounds, and provides better shot accuracy and first-hit probability thanks to its handheld Laser Range Finder. There's also a Day/Night Sight feature created by Insight Technology that allows shooters to maneuver and let off shots effectively in the dark.
