SMG - 7.62x51mm NATO - Germany - 700 RPM - While not a factory weapon, the HK 51 has been created by custom gunsmiths such as F.J. Vollmer from a combination of MP5 and G3 parts.  In other words, it is an MP5-sized G3!  While it maintains the power of the 7.62mm NATO cartridge, the blast and flash signature is at best unpleasant.  (c)D.E. Watters
