The Benelli Super 90 M4 also known as the M1014 Combat Shotgun is an Italian-made shotgun manufactured by Benelli Armi S.P.A. It is currently used by the United States Armed Forces as their "Joint Service Combat Shotgun". Touted in its make is the modular assembly basis of the weapon. It allows an operator to exchange the various assembly groups (barrel, buttstock, forearm, etc...) without tools. Especially useful in the field, the process is quick and allows the weapon to adapt to a changing tactical environment.
