guarantees shooting precision, reliability, durability and confirms the technological excellence of Benelli. 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. It is self-regulating because the gas inlet valve functions as a regulating valve that expels excess gas during firing.
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. is placed under the barrel, near the chamber, so as to exploit the hottest gases at a higher pressure. Made of a self adjusting gas system containing a short-stroke piston, A.R.G.O. Simple, robust, original, clever: these are the peculiarities of the project underlying the A.R.G.O.
