Milforum Mac Daddy
The Beretta Rx4 Storm
Designed by Beretta and Benelli engineers, the Rx4 Storm incorporates the most advanced technology in firearms. Using the ARGO (Auto Regulating Gas Operating) system perfected by Benelli, the gas port is located just forward of the chamber where the gases are hotter and cleaner, resulting in less fouling and more reliable cycling. The action bars are required to move only ½” for complete cycling which results in fast operation with minimum vibration, making it easier to handle and operate. Additionally, the position of the gas valves allows for the compact and lightweight design of this rifle.
