Built for Realism. Tuned for Reservoir Ducks.

The Mondo 2B is RNT’s take on John Stephens’ legendary J. Stephens Axe — a cut-down style call with enhanced backpressure, deeper tone, and more hold. It was designed with the real-world needs of reservoir hunters in mind, where finesse and realism are just as critical as power.

UPPERDUCK Exclusive Custom "Side-by-Side" Burn Line ("SXS") Acrylic Black Band with a Matte Finish. Also includes an authentic RNT stainless steel band.

“Where we hunt, the ducks already know where they’re going. I wanted a call that could produce soft clucks, chatter, and ultra-realistic quacks, but still had enough bark to break high ducks on migration days.”
