SMG - Suppressed - 9x19mm NATO - Germany - 900 RPM - The SMG-II was a prototype model meant to incorporate improvements over the basic MP5 design.  Only 60 hand-crafted copies were produced for an undisclosed government end-user.  A unique screw-in suppressor was designed for the SMG-II, and the base weapon had a selector allowing the suppressor to be set for either supersonic or subsonic ammuntion.  D.E. Watters
