How did we get from an H&R break open to a pump? Anyway, Remingtons interchange pretty close. A few years ago I got a .410 1100 barrel really cheap (new) and it had a full rib. I changed the ring (Had to silver solder) that goes over the extension tube and put sights on it and used it as a spare for the 870. It looks like they use bronze rods to weld the original on.
