You weren’t asking us to reinvent the M4—you were asking us 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 in H2O, FDE, or Multicam® Black and powered by Benelli’s proven ARGO gas system, the M4 EXT is the trusted platform—now fully loaded.
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.
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.
The M4 EXT is 922R compliant.
