I also have an 1100 30' vent rib barrel off of an older gun that has not been shot much at all. It is drilled for the wire catcher, Angle ported, long forcing cone, and the bore is shiny and unaltered. There is a small scratch near the muzzle. Bore is standard for the 1100's at approximately .730 X .690. PM me if interested, $200. Hope the pics come through.
