The Benelli M4 Tactical is a battle‑tested semi‑automatic 12‑gauge shotgun engineered around Benelli’s patented A.R.G.O. (Auto‑Regulating Gas‑Operated) system. This military-grade action utilizes twin self‑cleaning pistons acting directly on the rotating bolt, automatically adapting to a wide range of shell power without manual adjustments—ensuring reliability under the harshest conditions .
Standard with an 18.5″ barrel and a 5‑round magazine tube (with some LE variants offering 7+1), the M4 Tactical features a rugged synthetic pistol‑grip stock, fully adjustable LPA ghost‑ring rear sight, windage‑adjustable front blade sight, and a drilled‑and‑tapped receiver with Picatinny rail for optics or accessories . The model weighs roughly 7.8 lb with an overall length near 40″ .
Originally developed in response to a 1998 U.S. military solicitation, the M4 (also known as the M1014 in military service) has been adopted by the U.S. Marine Corps and other global forces after rigorous testing proved its ability to endure at least 25,000 rounds with minimal wear .
Praised by operators and experts alike, its robust build and simple, low‑maintenance design has earned it a reputation as a true “tactical tank”
It has been chosen by professionals worldwide and has been featured in films, including the John Wick series.
The Tactical Ordnance Benelli M4 is customized and tuned for the serious shotgun user and is available to end users bypassing the M4 1014 prohibition in Canada
