Function: Puts pressure on the tongue and corners of the bars. Each side of the mouthpiece moves independently. Turns onto a solid mouthpiece when asking for a stop.
Usage/Solution for: The Mullen Barrel mouthpiece is a good choice for the intermediate horse. With the strength of the solid mullen mouth, this bit encourages the horse to break at the poll, but keeps him from getting behind the bit, or inverting. The independent side movement allows rider to isolate one side and pick up a shoulder.
