I know this is a long shot. I bought a 5100 for a project gun. It has 24" barrels that must have been cut down. I plan to cut them down to 18.1" or so. But, the gun is ok for such an old thing. I'd like to get some original barrels for it, to preserve it and shoot it at an occasional SxS event, or once in a while for trap as a hoot.
