Benelli M4 Tactical 11713 – 2020 Italian-made, factory 7-round, ARGO-driven 12 GA powerhouse
The Benelli M4 needs little introduction to anyone who follows modern combat shotguns, and this 2020-dated, Italian-proofed example offers the configuration most enthusiasts try to build toward anyway: a full-length 7-round magazine tube, 18.5" chrome-lined barrel threaded for the Mobil-thread choke system, and a receiver already drilled and tapped for optics. With its USMC-proven Auto-Regulating Gas-Operated (ARGO) dual-piston action and robust manganese-phosphate exterior, this full-size 12 gauge delivers the reliability, modularity, and pedigree collectors and hard-use shooters prize.
Condition
Overall: Excellent. Only faint handling marks under close inspection; no finish loss, dents, or aftermarket alterations.
Bore: Excellent – bright, mirror finish with sharp forcing cone and no fouling.
Furniture & controls: Crisp checkering on the pistol grip and fore-end ribs; anodizing on the aluminum receiver remains even and unmarred.
What’s Included
• Benelli M4 Tactical 11713 shotgun (serial number within the 2020 “L20” block)
• Flush Medium (M) Mobil choke installed
• Original Benelli choke wrench
• Factory owner’s manual and lock
Why this particular M4 stands out:
• Factory 7-round magazine tube – no extensions, no roll pins, and no 922(r) parts hunt.
• ARGO self-cleaning gas pistons – the same system that cleared the U.S. Joint Service Combat Shotgun trials for extreme dust, sand, and temperature tolerance.
• MIL-STD-1913 top rail – mount an RMR, Aimpoint, or LPVO without surrendering the protected front post and adjustable ghost-ring irons.
• Mobil-thread choke system – rare on tactical M4s and ideal for tuning pattern density with flush or extended tubes.
• Italian proof marks and matching “BENELLI USA CORP – ACCOKEEK MD – MADE IN ITALY” roll marks, certifying true Benelli factory origin rather than later U.S. contract assembly.
• Parts commonality with the military M1014 – stocks, handguards, and triggers swap in minutes for mission-specific setups.
• 14-3/8" length of pull and fixed pistol-grip stock – a sweet spot for maintaining control with full-power 3" buck or slug loads.
Whether you’re completing a service shotgun collection, setting up a duty rig that must run when everything else quits, or simply want the benchmark semi-auto 12 gauge in its most desirable factory trim, this 2020 Benelli M4 Tactical delivers the performance and provenance to justify its place in the safe and on the range.
