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 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.
