Benelli M4 Tactical Shotgun: 12 Gauge-3", 18.5" Barrel, Model A0223100

Sets The Standard For Tactical Shotguns.

This is the foundation on which all Benelli M4 Auto-Regulating Gas-Operated (A.R.G.O) semi-automatic shotguns are built. The A.R.G.O. system makes them fast cycling and ultrareliable. Optimized for tactical response and personal defense, the M4 features a tactical stock, adjustable rear ghost-ring site, windage-adjustable front sight, and a Picatinny rail for a light or optics.

Auto-Regulating Gas-Operated - U.S.M.C. Approved

This piston-driven Auto-Regulating Gas-Operated (A.R.G.O.) system was designed for and approved by the U.S. Marine Corps.

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 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.
