The second generation of our popular J Frame... We've increased the barrel length slighty, added some more lift to the toneboard, and built in a little more hold for those days when you need a little more finesse. The swamp fox is a medium range traditional single reed duck call. It has an O-ring and a friction fit for double security.For the 2017-2018 season, the swamp fox will be offered in Black Gold, Mallard Green, Chartreuse, and matte Black.
