Model 870

The Remington 870MCS Combat Shotgun is a pump-action shotgun used by the U.S and Australian Military. Unlike a standard 870 Shotgun, the 870MCS has a modular design, with many RIS Rails. This allowed wielders to attach optics and other attachments on the weapon with ease.

Battlefield: Bad Company
In singleplayer, the 870MCS can be found in a few missions. It is the weapon that Haggard always uses other than his AT-4 Anti-Tank Rocket Launcher.

In multiplayer, it is the default shotgun issued to the American "Demolition" kit. It has an 8-shell capacity (7 in tube; 1 in the chamber). Like all pump-action shotguns, it is very powerful, being highly capable of killing in a single shot, but its efficiency deteriorates quickly at longer ranges. It is also limited to a low rate of fire, requiring the user to pump every shot. When possible though, the 870MCS might be preferable over other pump action shotguns due to its faster pumping action and therefore rate of fire.

Battlefield: Bad Company 2
In multiplayer, the 870MCS is the first shotgun available to the player. It acts much like the one in Battlefield: Bad Company, only its rate of fire is higher, it has a default capacity of 4 shells and increased range. If used with the Shotgun Extended Mags Spec it can hold 8 shells, making much more effective in combat.

Trivia

 * In Battlefield: Bad Company, the 870MCS has the exact same stats as the MEC T194. The reason for this is balancing purposes.
