A.R.G.O. ®
Simple, robust, original, clever: these are the peculiarities of the project underlying the A.R.G.O. patent: : A.R.G.O. stands for Auto Regulating Gas Operated. Made of a self adjusting gas system containing a short-stroke piston, A.R.G.O. is placed under the barrel, near the chamber, so as to exploit the hottest gases at a higher pressure. The gases tapped from the barrel expand (in the self adjusting gas system) and rapidly accelerate the stroke of the piston, which simultaneously hits the bolt follower pin and pushes it hard to enough to make it retract. It is self-regulating because the gas inlet valve functions as a regulating valve that expels excess gas during firing. The greater the volume of gas flowing from the barrel, the faster the pin valve opens and allows it to exit, thus decreasing the pressure inside. Self-adjusting, A.R.G.O. guarantees shooting precision, reliability, durability and confirms the technological excellence of Benelli. An operating mechanism that is also appreciated and approved by the Marines.
