Rolling Thunder Game Mean Duck J-Frame Game Call Ducks Ivory. It brings that crunchy "hybrid" style sound to the line of calls. Its much easier to operate than a cutdown but still packs that raspy deep tone of a cutdown. The MeanDuck is compact and responsive delivering the full range of rasp that today's duck hunters expect. The unique bore system we built into this call delivers a lot of punch while retaining enough back pressure to allow for ample forgiveness when air presentation is less-than-ideal.
