Here we have a mallard duck call with a lot of different wood barrels and a acrylic insert. the insert is a insert of my own design. These calls have my Mrs. h insert. The inserts have a Oring seal, so you will not have any air leakage. These calls have a great duck sound, from the feeding chatter, to the high balls of the mallard hen. These calls are also great looking calls at a great price. the woods change as calls are sold, so if you are looking for a certain kind of wood, contact us. you will not be disappointed with one of our calls.
