The Dickinson XXPA delivers high performance and consistency in a reliable and durable semi-automatic shotgun design. It comes chambered in 12GA with a 3 inch chamber and an 18.5 inch barrel. Features include a synthetic stock, a ghost ring front sight, Picatinny rails, and a 5 round capacity. In semi-automatic mode a gas piston drives a bolt carrier; in pump-action mode the same components are driven by sliding the fore-end backwards. - CHAMBER 12GA 3" - MAGAZINE (3) 5rd capacity - SIGHT Front Ghost Ring - CHOKE Breacher Cylinder Bore
