The Benelli Model M4 Tactical Semi-Automatic Shotgun is a no-nonsense shotgun that the US Marines, police and military the world overreach for when the going gets tough. The unique Auto Regulating Gas Operated (A.R.G.O.) system developed by Benelli engineers has dual stainless steel, self-cleaning pistons located just ahead of the chamber that operate directly against the bolt assembly. The metalwork is chrome-plated, and comes with the option of black-anodized or coated with heavy phosphate to prevent corrosion under the most grueling conditions. This model features a telescoping stock, a 7-round magazine tube, and comes with tritium night sights.
