The RF-03 Dirty Rice Mallard Call. This is a Cajun Squeal style of call that has been popular in getting the sound of mallards when they are feeding on rice. The barrels have been designed so that it is easier to get the squeal out of this double-reeded call. We’ve even included the Tony’s creole seasoning for the dirty rice, so get to cookin’ . . . AHHH eeee!
