I just set up one of my Rem 870 slug barrels with Tritium Night sight for Coyote hunting in low light. The barrel has open sights and screw in chokes. I replace the rifled Rem Choke with a pattern master and will be using 3 inch number 4 copper plated buck Federal Premium. The tritium night sights work great on this shotgun. I personally don't like scopes on shotguns except for slug shooting.
