I have the comp-n-choke on my 835 and it throws one heck of a pattern (190-200 #5's in a 10" circle @42 yards) As I understand it the comp-n-choke and kicks are made from the same company. If you want to shoot hevi shot or ever plan on it I would make the investment($90) in a rhino choke have never heard one bad thing about it and some of the patterns I have seen are amazing.
