AA-12, Automatic 12-gauge Shotgun, has a long an interesting 40+ year history

Starting back in 1972 when Maxwell Atchisson created the Atchisson Assault Shotgun

Atchisson Assault Shotgun
2 3/4" Magnum

5-shot box magazine
Blowback, Open Bolt

11.46 lbs (5.2 kg) empty
14.32 lbs (6.5 kg) with loaded 20-shot drum

It was never perfected, then in 1987 Max sold the rights and designs for his AA-12 to Jerry Baber (Military Police Systems, Inc)

Auto Assault-12
2 3/4" Magnum
3" Shells

300 rounds per minute
Five 12-gauge shotgun shells per second

8 box magazine
20-shot or 32-shot drum magazine
open bolt, gas-operated with a locked breech

10.49 lbs (4.76 kg) empty
13.35 lbs (6.06 kg) with loaded 20-shot drum

In the early 1990's Boje Cornils was hired on to improve the design and set up the tooling to produce the AA-12

188 Changes & Improvements

We had the opportunity to meet and interview Jerry and Boje to get first hand information on the development and operation of this unique and popular automatic shotgun

Slowly, more of the AA-12 are being made, but because newly built machine guns are not transferable to most of us according to the Hughes Amendment of the 1986 Gun Owners Protection act, and only government and police agencies can buy these, the market is not very large, and most sales are exports to other governments

A semi-automatic version of the AA-12 would undoubtedly be considered "non-sporting" by the ATF and therefore regulated as a "Title II" Destructive Device with extra paperwork and a tax stamp

Thanks to Jerry, Dotti and Boje
