The RNT Calls MVP Acrylic Duck Call stands for maximum volume and performance. This is the ultimate competition style duck call. Expanding on their extremely successful Original contest model design, Rich-N-Tone has made a few changes on the tone board along with adding a uniquely designed wider bore to the insert to give you a looser handling, from top to bottom call. Its bore also allows you to hit the top as well as the bottom harder than the Original, giving you the maximum volume and performance needed to produce contest quality top-end hail calls and bottom end duck. Even with the Original's unbelievable competition track record we think it's safe to say that the torch has been passed. Single reed. Material: Acrylic.
