The Benelli M4 Tactical shotgun is a unique, Auto-Regulating Gas-Operated (A.R.G.O.) semi-auto. The M4 Tactical is the combat service shotgun of the U.S. Joint Services today.

Battle-proven reliability

Picatinny rail for mounting scopes, sights, and optics

Ghost-ring sights for quick target acquisition

Originally designed in 1998 for the U.S. Marine Corps, the M4 (M1014) was extensively tested at the Aberdeen Proving Ground in Maryland. It proved totally reliable for safety, function, and performance.

For reliability when it counts, select the M4 Tactical shotgun.

A combat shotgun has to function the first time, every time. The Benelli M4 does it for the U.S. military, and now can be the centerpiece of your own home defense plan. Troops who fight day and night need heavy accessories like night vision scopes. The combined additional weight of these optics and other accessories is not a problem for the M4. Benelli engineers developed and patented a unique auto regulating gas operated (ARGO) system. Dual stainless steel self-cleaning pistons located just ahead of the chamber operate directly against the proven rotating bolt and eliminate the need for complex linkages found on other gas autos. The result, Marine-tough reliability under the harshest environmental conditions.
Ghost-ring sights are click-adjustable using a cartridge rim, and can be ordered with tritium inserts for low-light operations. A Picatinny rail allows the mounting of scopes, red dot sights or night optics while retaining back-up metallic sight capability. 4+1 capacity. Buttstocks can be changed without tools to suit your needs. Ships with pistol grip stock, now OK to add M4 collapsible stock (optional, may be hard to find).

This piston-driven Auto-Regulating Gas-Operated (A.R.G.O.) system was designed for and approved by the U.S. Marine Corps.Benelli’s patented Auto-Regulating Gas-Operated (A.R.G.O.) system is a simple, self-cleaning, piston-driven action.

The A.R.G.O. system is a unique, short-stroke, dual-piston design developed for the M4 Tactical shotgun in 1998 for the U.S. Marine Corps. It was later adopted as the U.S. Joint Services combat shotgun-and remains so today.

The Benelli R1 Big Game Rifle is built around the same, patented A.R.G.O. piston-driven system developed for the M4 Tactical shotgun.

The gas port is located just forward of the chamber, where the gases are hotter and cleaner. This results in less fouling and more reliable cycling.

Pistons push directly against the bolt, for fast operation and minimum vibration.

There are no connecting linkages or heavy action bars under the forend, which add weight.

The torque locking system in the R1 Big Game Rifle ensures repeatable accuracy, because barrel tension remains constant for every shot.


Nice gun

Put 200 rounds of Light Brass and heavy brass 00 and never missed a beat.


Dominate your defense

If you want the ultimate in static defense, look no further than the Benelli M-4. The Benelli M-4 works as advertised. It will fire five (5) rounds of 12 gauge fury in .6 seconds. As far as breaking contact or dominating a sudden encounter, there is no more devastating man-portable weapon than this shotgun loaded with 00 buck. Recoil is completely managable and this gun is super reliable. In a world of uncertainty, the Benelli M-4 is a certain way to repel an attack.


This is the shotgun you want.

This thing has been my favorite firearm I’ve ever owned. Sure, it’s not a duck gun. If you want a duck gun, look elsewhere. You could use it for that, but you guys always want your camouflaged ones. Anyway, this thing love 00 buck and slugs. Be prepared to go through a couple ten or dozen boxes of shells the first time you go shooting. If you don’t have a shooting addiction prior to shooting this, you will. Keep it at home, at the ready. 🙂 Don’t underestimate the deadliness of this shotgun. There’s a reason the US Marine Corps carries this.

This is by far the finest shot gun I have ever fired. Action is buttery smooth and solid as a rock. The hotter the load, the more she likes it! Slugs and 00 buck all day without a hiccup. It may seem expensive, but one squeeze of the trigger… instant gratification. DO IT! And all your gun buddies will be begging you to shoot it!

As Military Police in the United States Marine Corps, these are what we carry both in our patrol vehicles while we are on patrol and at the entry control points to the base. I’ve taken these out to ranges multiple times and just can’t seem to say enough about them! They fit perfectly into your hands, whether big or small, it carrys well when in a sling, either over your back or over your chest, and it finds that sweet spot in your shoulder almost effortlessly. Overall this is the best shotgun I have ever had the pleasure to unload and enjoy thoroughly. The only difference between this weapon and the ones we carry is the tube, our’s will hold seven plus one in the chamber. 00 buck and slug staggered, makes a deadly combination.
