This very particular 12 gauge shotgun is being in fact produced will be produced in a semi-auto only version by Sol Invictus Arms, a new US based company created by the team at Tactical Superiority, Inc., manufacturer of high-quality OEM parts used by many well-known firearm firms.

The full-auto shotgun concept was originally developed by Max Atchisson in the 1970s who called it  “Atchisson Assault Shotgun”. In 1987 the rights were sold to  Military Police Systems, Inc., a Tennessee company, and its name was changed in “Auto Assault 12”. The design underwent a long series of modifications and refinements, still retaining a rate of 300 rounds per minute. Over an 18 year period, more than 100 mechanical and functional component parts were modified or re-designed, including the changing from a blowback- to a gas-operated action with a locked breech.
