Compact Battle Rifle Supressed - 7.62x51mm NATO - Germany - 600 RPM - The G3K is the carbine version of the basic G3 rifle, intended for armored vehicle crews and other troopers requiring a compact rifle.   Utilizing a retractable stock and possessing a shortened barrel, the G3K still maintains the same sight radius as the full-size G3.  D.E. Watters
