hastings, comp-n-choke, mad max turkey tube, briley, truglo. They all are good & all will work if you can match up your shells & choke to get a good pattern. I currently use hastings & have for years. I have had great luck with them & I really like the .660 choke for #5 or #6 shot. I have also patterned the comp-n-chokes & they are great too. I have also heard a lot of great things on the truglo's.
