Photo Of The Day, and with permission, we’re sharing Beach Ballistics’ images of his Remington 870 Modular Combat Shotgun (MCS). All configurations share the same 870 receiver, streamlining maintenance, training, and logistics.

The MCS system allows users to quickly switch between multiple barrel lengths and stock configurations. This is made possible through a quick-detach system for barrels and stocks, and it's designed to adapt the shotgun to various mission profiles. for instance. the 10” Breacher barrel for entry and breaching and the 14” and 18” barrels for tactical or patrol use.

Swapping barrels or stocks can be done in the field without any major tools.

What most people don’t realize is that the shotgun is one of the most violent firearms available.


The forend includes Picatinny rail options for attaching tactical lights, lasers, vertical grips, and other mission-specific accessories.

The obvious question is, of course, which configuration do you like best?

    How many people really swap all that stuff around and use the different configurations beyond just messing with it? How many commercial/govt/military users REALLY use the different configurations of fire control pistols with different modular grips, frames, etc?

    I wanted this gun so bad... until i was issued one. It is the WORST shotgun I have ever had the misfortune to use. I'd take a Mav 88 over this, and even a clapped out 590 is objectively better.

    Anomanom: You don't want the forend. It puts so much recoil right into you finger. It is not fun, especially when you are doing corners.

    Hoyden: Nobody. The military talks modularity but never uses it.
