The Spitfire SMG
They made the A10 Warthog a gun! I wonder if they'll make a washing machine gun next?
This bullpup SMG may shoot pistol rounds but its lethality isn't a joke. It loosely follows the same design as the Vesper and Raijin EMX, so cross compatible magazines will be a thing between these three.
Features
Extendable stock at the rear, picatinny and muzzle mounts in the front. Make it fit your profile however way you feel comfortable, and watch as it bounces like hell anyways.
