The street sweeper shotgun has nothing to do with the AA-12. It was designed in 1980 by a Rhodesian man named Hilton Walker. The AA-12 on the other hand was developed in 1972 by Maxwell Atchisson. While the AA-12 is actually fully automatic, the street sweeper uses a wind up mechanism in the drum mag and functions semi auto.
Always loved this shotgun, practically the precursor of the AA-12. :D
