An automatic choke system for automatically adjusting the amount of choke applied to a series of shots discharged from shotgun. The automatic choke system includes a tube assembly with a plurality of longitudinal slits within the distal end thereof, a collar unit attached about the tube assembly, and a swedge assembly slidably positioned between the tube assembly and the collar unit. A latch unit attached to the collar unit selectively allows the swedge assembly to move forwardly one position after each shot fired. The latch unit is operated by gas flow from the interior of the barrel of the shotgun during a shot.
