If you're familiar with M32s then this operates in much the same way, just in a nicer looking package. Unlike M32s however, most of this is made from metal. This means that despite its compact size, the Revolver Launcher weighs in at 3.4kg.
 
Modifications may be required to fire TAG rounds (or it may not, I haven't tested to confirm at the risk of frightening the neighbours ear drums)
