Remington 870 Marine Magnum, 12 ga. pump action firearm. Serial #RF24133A. Like new condition, appears unfired. 14" Cylinder choked 3" magnum barrel. Small black synthetic butt. Very short and quick! SF light system under barrel that serves as forearm as well - controlled with left finger pads. Appears no batteries inserted. Nice for home defense when a very short weapon is required. Gunrunner West item.
