Just got a new Harris bipod and they have changed the bolt that puts tension on when you secure it onto the stock. Instead of a cross-slot that bolt now has an allen-type recess in the center and a large serrated outer head that makes hand-tightening doable. This is a good idea, makes a great bipod even better. This switch was implemented a year ago. Not sure if you guys are aware but Outers is marketing an identical bipod now, only difference is the "Made In China" stamped on the bottom.
