With this volume of Big Bang, we focus on the RHINO and CAWS projects implemented by the US military between 1979 and 1994. These projects were dedicated to the development of automatic shotguns for combat use in urban environments, earthwork environemtns, and aboard navy vessels. In the end, the programs resulted in numerous functioning automatic shotguns, but in the end, it was decided these weapons were simply too deadly to be in compliance with the century old Hague Convention used as a guide to conducting modern warfare.

This volume covers more than 20 models and variants of automatic shotguns developed between 1972 and 1994, including:

• the Atchisson Assault Gun developed during the Vietnam War.
• the AA12, the second generation of the Atchisson.
• The Daewoo USAS-12, the third generation of the Atchisson.
• The Pancor Jackhammer
• CAWS prototypes from Heckler & Koch, Aircraft Armaments, Inc. and Smith & Wesson.
