Dickenson Commando Marine w/ a pump action system. Chambered in 12ga w/ 20" barrel and 5+1 rds capacity. Dickinson pump shotguns are built using a new design that allows for superior strength, ease of operation, and reduced weight. All Dickinson pump shotguns feature double slide bars and a convenient action release forward of the trigger guard that can be operated while wearing gloves.
