The Benelli M4 has earned its reputation through decades of proven reliability, and has forged a legacy built on trust and has served military professionals, law enforcement, and home defenders with unmatched consistency.
Now, the legendary M4 is available with several of the most requested enhancements, including 7+1 capacity off the rack.
Introducing the M4 EXT: the same battle-proven M4, now equipped with more of everything that matters—capacity, adaptability, and speed.
This new model was built for those who push their gear hard and demand upgrades that don’t compromise reliability. The M4 EXT delivers:
- A 7+1 round capacity—finally giving shooters the firepower they expect
- A 5-position collapsible stock with integrated pistol grip for a precise, locked-in fit
- An oversized bolt release, optimized for fast engagement—even with gloved hands
- Three striking finishes: H2O, FDE, and Multicam® Black
At the core is Benelli’s trusted Auto-Regulating Gas-Operated (ARGO) system—a dual short-stroke piston design known for cycling clean across all loads, with minimal maintenance and maximum reliability.
“Consumers weren’t asking us to reinvent the legendary M4…they were simply asking us to unleash it. Now we have.” said Bret Maffet, Senior Product Manager, Benelli.
