The Remington Versamax is a 3.5-inch chambered flagship semi-auto using the VersaPort gas system — eight ports in the chamber area that self-regulate based on shell length. Shorter shells cover more ports, bleeding more gas; longer shells cover fewer ports, using the gas more efficiently. A fundamentally different approach to universal cycling. Type: Semi-Auto Shotgun Action: Gas-Operated Caliber: 12 Gauge Capacity: 3 Year introduced: 2011, USA Weight: 7.7 oz Overall length: 49" Status: Discontinued Intended use: Waterfowl, Field, Hunting
