Benelli M4 Tactical 12 Gauge Semi-Automatic Shotgun — 18.5" Chrome-Lined Barrel, Full-Length Tube, Ghost-Ring Sights
Benelli’s battle-proven M4 Tactical stands out for its Auto-Regulating Gas-Operated (A.R.G.O.) dual-piston system, reliable across a wide range of 2 ¾" and 3" 12 gauge loads. This example, proof-dated 2020 and built on a matte-black 7075-T6 aluminum receiver, includes the desirable full-length 5 + 1 magazine tube and the same ghost-ring sighting system adopted on the U.S. Marine Corps M1014. Clean, lightly used, and ready for duty or defense, it offers collector appeal and real-world performance in one package.

What’s Included
- Original Benelli factory cardboard box
The M4’s A.R.G.O. dual-piston system uses two short-stroke stainless pistons positioned just forward of the chamber, reducing fouling and ensuring fast, reliable cycling with standard or magnum loads. Its fixed, pistol-grip synthetic stock gives a 14" length of pull and ends in a rubber butt-pad that helps tame recoil.
An 18.5" chrome-lined steel barrel with interchangeable choke threads delivers durability and easy pattern tuning. Benelli’s wing-protected front post and fully adjustable ghost-ring rear sight provide a clear, fast sight picture in any light.
The receiver and barrel wear a uniform matte-black hard-anodized finish that resists corrosion and glare. True to its tactical role, the shotgun includes an integral Picatinny rail for mounting optics or accessories without modification.
Marked with Italian PSF proof marks and a 2020 date code, this recent-production example matches its receiver and barrel serials—a detail valued by collectors seeking factory-original integrity.
With the full-length magazine tube installed from the factory, this M4 ships at its optimal 5 + 1 capacity, ready for defensive or competition use straight out of the box.
