You weren’t asking Benelli to reinvent the M4—you were asking them to unleash it.
The new M4 EXT delivers just that: more capacity with a 7+1 loadout, more control with a 5-position telescoping stock, and more speed with an oversized bolt release made for gloved hands and high-stress reloads. Finished FDE and powered by Benelli’s proven ARGO gas system, the M4 EXT is the trusted platform—now fully loaded.
MORE CAPACITY:
- 7+1...FINALLY. Built to carry more so you can push harder. Whether you’re clearing rooms or defending your ground, extended capacity means fewer reloads and no hesitation under pressure.
MORE VERSATILITY:
- FIVE POSITIONS. FULL CONTROL. Adaptability isn’t optional—it’s essential. The M4 EXT’s 5-position stock delivers a custom fit in any scenario, from body armor to bare shoulder. More versatility means more control, no matter what you're up against.
- H2O. FDE. MULTICAM. These aren’t made to stand out—they’re made to take over. Each finish is selected for a mission: corrosion resistance, low visibility, or full-pattern dominance. No shine. No flash. Just options built for those who move with purpose.
- UNFAILING — BY DESIGN. Benelli’s ARGO system is the heart of the M4 EXT—dual short-stroke gas pistons built to run clean, cycle anything, and keep firing through dirt, heat, and high round counts. It’s self-cleaning, low-maintenance, and brutally reliable. No tuning. No gimmicks. Just a system that refuses to fail.
