The MAD Super Max which was made by Indian Creek is .695, and it looks like an Indian Creek choke. The other long MAD chokes for the 835 were made in .680 and .690. I have the .680 choke. These chokes I believe were made by whoever Lohman chokes were made by is my conclusion. They shot pretty good. But not as good as other great chokes that are currently on the market. I do have a MAD Super Max .675 choke for my Remington that shoots as good as any choke I have tried.
