"The thing I never could figure out about Shotgun's was why a CQC weapon had to be so long? You try swinging that thing around in 3 foot hallways. It don't work that way. But this thing, ah, now it's a different story. Necros beware!"
―Anonymous Marine

The M77 Extreme Close Quarters Combat System is an ultra-light UNSC shotgun, used for missions in extremely tight quarters. It can be used as a small, light-weight shotgun, or as an underslung weapon.


The Shotgun is a semi-automatic, magazine fed weapon. The shotgun is semi-automatic, with a reciprocating gas system.

The shotgun has a removable hollow stock, which can be adjusted and removed allowing it to be exchanged and fitted to a assault rifle. The grip can be exchanged for a smaller, lower impact grip to allow close quarters combat. A Misriah Rail runs continuously along the receiver, with another rail under the barrel and one to each side of the barrel. When fired, the bolt of the M77 travels down into the receiver, taking recoil away from the shooter. It has fully adjustable and removable day/night iron sights.

The shotgun is used by special forces, airborne units and boarding teams, and is also seen attached to rifles by regular forces operating in urban areas, mostly for door breaching and clearing operations.
