The Rocky Mountain Hunting Calls Little Big Mouth Bugle Tube Elk Call comes in weighting only 9 ounces, which makes it extremely easy to pack in the mountains. The all-aluminum tube creates high screaming bugles with crisp clear notes and creates more volume than most full-size bugle tubes. The Little Big Mouth utilizes the V.E.T.T. system mouthpiece for a 1 1/2” mouth opening, and a narrow throat requires less air and creates optimal back pressure. The tube is covered by a water-resistant padded cover to eliminate unwanted sound while walking, and to keep your hands off of cold aluminum on those crisp fall mornings and evenings.
