The Remington 870 is a 12-gauge pump-action shotgun built with an aluminum receiver and aluminum stock. It features a 19-inch barrel and a standard magazine capacity of four rounds. The configuration follows the classic 870 layout, utilizing a manually operated slide action for chambering and ejection. The aluminum construction contributes to a lighter overall weight while maintaining strength for repeated cycling. The design accommodates standard 12-gauge shells and supports smooth operation through its pump mechanism.


Core components include the barrel, receiver, and stock—all specified in aluminum—providing a uniform material finish across major assemblies. The 19-inch barrel length places this configuration in the shorter category for the 870 series, suitable for users seeking compact handling characteristics within the pump-action format. The receiver design supports the typical 870 bolt and carrier system, with the four-round capacity aligning with standard magazine tube dimensions for this model.
