Rich N Tone Calls designed the short barrel duck call to be snotty, whiney, but not obnoxiously loud. Marred as the Originals little stepbrother, the Short Barrel has become the nastiest, gnarliest, plain out “bad to the bone” call, ever packed in a 4 1/4 inch duck calling machine. It’s intricately designed toneboard along with its shorter barrel makes for an easier blowing call as well as allowing the caller to come down softer on the call without sacrificing a meaty ducky sound on top. The bore was designed to produce a nasally ducky sound with just the right amount of back pressure to make this an unbelievably awesome, medium volume call. Single Reed. Acrylic.
