RNT's MVP: Maximum Volume and Performance. The ultimate competition style duck call! Expanding on their extremely successful Original contest model design, RNT has made a few changes on the toneboard along with adding a uniquely designed wider bore to the insert to give you a looser handling, from top to bottom call. It's 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. Perfect for the contest stage, and extremely effective on ducks, the MVP is a solid choice for any duck fanatic.
