This is Remington's entry level competition shotgun. The versa max is based on the benelli M4 gas system. The Benelli m4 gas system is a dual piston design. It runs just about anything that will fit in the gun. Since I run a Benelli m4 for three gun, I naturally like the shotgun. It is better suited for 3 gun competition out of the box. In short I like the shotgun.
