TRIARC Benelli M4 Upgrade Service

The battle-proven Benelli M4 Tactical Shotgun has earned its stripes in reliability, serving the U.S. Marine Corps since 1998. It operates through an exclusive Auto-Regulating Gas-Operated (A.R.G.O.) system, boasting dual stainless steel, self-cleaning pistons directly on the bolt assembly. This unique mechanism eliminates complex linkages and hefty components found in other semi-auto shotguns, ensuring a simpler, sturdier action.

Capable of handling anything from standard field loads to robust 3″ buckshot without requiring adjustments, the auto-regulating gas system is a standout feature. Crafted with a pistol-grip synthetic buttstock designed for resilience in any environment, the rubber/poly blend grip combined with a solid recoil pad significantly reduces recoil and muzzle lift. This allows shooters to maintain accuracy and swiftly fire follow-up shots.

For enhanced versatility, there are under-barrel sling points at the handguard’s front and on both sides of the stock, enabling ambidextrous sling attachment. The shotgun features an 18.5″ barrel equipped with a modified screw-in choke tube and a 5-round magazine tube. Safety is ensured by a crossbolt safety positioned behind the triggerguard.

Equipped with a fully adjustable LPA ghost ring rear sight and a white dot front blade enclosed in protective ears, the Benelli M4 allows for rapid target acquisition. Additionally, a 5.25″ Picatinny rail permits users to mount extra scopes and optical sights.

The Benelli M4 stands as an excellent choice for home defense, law enforcement, or as a reliable all-purpose shotgun, ideal for traversing bear country.
