The Beast Acrylic Single Reed Duck Call by Rolling Thunder Game Calls is built for hunters who demand aggressive volume and unmatched control in the blind or timber. Hand-tuned from high-quality acrylic, this call delivers sharp, raspy mallard sounds that cut through wind, weather, and hunting pressure. With lightning-fast response, explosive volume, and finesse on the low end, the Beast lives up to its name—and is a deadly choice for serious waterfowlers.
