If your life depends on it, depend on the no-fail reliability of the Benelli M4 Tactical 12 GA 18.5″ Tactical Stock Semiautomatic Shotgun. These Devil Dog-approved defense shotguns boast a unique Auto Regulating Gas Operated (ARGO) system that guarantees rapid-fire reliability.  Benelli’s ARGO system is a unique and simple self-cleaning, short-stroke piston-driven action that was designed for the US Marines and was later adopted as the U.S. Joint Services combat shotgun and remains so today.

The gas port on the ARGO system is located just forward of the chamber where the gases are hotter and cleaner, resulting in less fouling and more reliable cycling. Pistons push directly against the bolt for faster operation and fewer vibrations. Extended magazine tube and lightning-fast semiautomatic firepower at your disposal mean maximum downrange effect. Comes standard with a Picatinny rail, standard modified choke tube, fully adjustable ghost-ring rear sight, fixed-blade front sight, and synthetic tactical buttstock.
