This Buck Gardner Acrylic Mallard Hammer custom double reed duck call has 45 degree individually cut reeds and SBT (Short Barrel Technology) that allows a feed call that is Super-Free and Easy. The heavily dimpled top reed makes it virtually impossible to blow a tone out of the call. This call will bark with the biggest dogs and still whisper sweet and sexy on the bottom end. Double Silicone Coated O-Rings that help ensure a perfect fit between the insert and barrel. Available in Black Barrel with MPW logo and Ivory insert.
