MP7A1 upper Left, showing it with the reticule sight and laser pointer removed, sliding stock extended, and the pistol style foregrip in the down position.

Upper Right, Ruger MP-85 with target-shooting razzmatazz removed.

Below, a toy MP5 made by Ming Sheng. It most closely approximates the MP5K designation, but picatinny rails have been added for a laser pointer (right side) and sights of some sort. The non-sliding stock is removable, as is the fore grip and suppressor. H&K calls this a PDW, or Personal Defense Weapon rather than assualt rifle.
