This piece of shaft came in a factory Smith and Wesson box, made to fit, blue colored box was marked I-bolt 15 oz. Recoil reducer, part number 402080000, the shaft itself looks like cold rolled steel, cut on a lathe, etched i-Bolt, Smith and Wesson, 150z. Magnum Recoil reducer. I don't think this is a scam on the sellers part, it IS a S&W factory item........or at least WAS, probably discontinued now.
