The Benelli M4 delivers a very rapid action that fires, extracts, ejects, and loads in the blink of an eye. Something about delivering payloads of shot per trigger pull is just so satisfying. The M4 variants come with replaceable chokes in the Benelli/Mobil pattern. I replaced the optic’s mount with a Scalarwork Sync mount and attached a Holosun 507C. Additionally, the M4 comes with ghost ring peep sights and an optics rail. The gun comes with a plastic, two-piece handguard which is completely sufficient but does not offer mounting capabilities. The only downside ergonomically for the M4 is that dang bolt release. The safety is a crossbolt behind the trigger, and the bolt release is placed slightly below the ejection port. The controls include a charging handle on the right-hand side, a bottom loading port, and a right-side ejection port. The Benelli M4 holds five rounds from the factory, and with the proper tubular magazine, it holds seven rounds. The Benelli M4 uses a gas-powered system known as ARGO. This dual gas piston design required very little maintenance and eliminated the need for linkages which simplified and lightened the design.

The ARGO system, in particular, was quite revolutionary. The Benelli M4 was the first Benelli to move away from the famed inertia system the M1, M2, and M3 utilized. With the tube, handguard, the Benelli three-position stock, and a few other parts and pieces, I had what I considered a proper combat shotgun. This includes an American-made seven-round tube and Mesa Truckee handguard. To legally return the M4 to its glory, I went with Freedom Fighter tactical to obtain the American-made parts necessary to validate 922R. Mine came with a fixed stock and five round tube. Since the ATF hates freedom you’ll have to use American made parts to get the 7 round tube
