Ryan, the Maxus II is the re-provisioned version with many user inspired updates. Lighter, smoother edges, more balanced barrel to stock geometry, and a recoil absorbing pad for less shoulder stress. Rubber molding for better grip and better ergonomics make the choice crystal clear between the two. Cheers and stay safe!

Id go with theMaxus II all the way.
The new Maxus II shares the same foundational design and performance features that have made the original so revered, and includes an array of new refinements that will give you the edge in the field and in competition. The Maxus II is sleeker for a smoother swing and more intuitive pointing. A new Inflex Technology recoil pad and SoftFlex cheek pad combine to further reduce the recoil you feel from a day in the goose blind or the sporting clays range. Rubber overmoldings improve grip and oversized controls are easier to use. The forearm and magazine have been redesigned with a traditional, screw on cap.
Combined with the proven reliability of the orignal, the evolutionary improvements of the Maxus II have elevated the versatility, performance and handling of this already tremendous shotgun. The Maxus II is the shotgun with the goods to bring your game to the next level.
