12 guage, 2 3/4" shell, 28" length, fixed choke Remington barrel. I'm not sure if it is for a 870 or? If you can help me ID the shotgun model, I would be most appreciative. There is no choke stamped on barrel. Barrel is in excellent condition, with no rust, scratches or dings, and bluing is in great shape overall. $60 shipped. Thanks for looking!
