7+1 Extended Capacity

Extended magazine tube provides 7+1 capacity in 12 gauge—increased over the standard M4's 5+1 configuration. The additional rounds reduce reload frequency for defensive and tactical applications.

ARGO Dual-Piston Gas System

Auto-Regulating Gas-Operated (ARGO) system uses dual stainless steel short-stroke pistons positioned ahead of the chamber. The self-regulating design cycles 2.75" and 3" loads without manual adjustment and resists fouling under sustained fire.

5-Position Telescoping Stock

Five-position telescoping pistol grip stock adjusts length of pull from 9.25" to 14.375". The adjustable range accommodates varied shooter builds and body armor configurations.

Ghost Ring Sights and Picatinny Rail

Ghost ring rear aperture sight with windage-adjustable front post. Integrated Picatinny rail on receiver for red dot or optic mounting. Drilled and tapped receiver.

Titanium Cerakote Finish

Titanium Cerakote on barrel, receiver, and stock provides corrosion resistance and consistent appearance throughout.

922R Compliant

922R compliant configuration for US import compliance. The Benelli M4 EXT delivers extended-capacity ARGO reliability—7+1 with 5-position stock and Titanium Cerakote for tactical and defensive 12 gauge applications.
