Buck Gardners Buck Brush Polycarbonate Duck Reed Call - Buck Gardner took the proven design of the legendary Buck Brush acrylic single reed call and engineered it in a polycarbonate version. The Buck Brush is crisp, loud, and has a personal touch that most call makers reserve for custom acrylic calls. It has a shorter barrel for improved air control and operation. Each polycarbonate Buck Brush has a hand-sanded toneboard and fitted with hand-trimmed reeds and real cork to ensure performance well in excess of the price.
