The MB 41PB is a truly unique Myler mouthpiece. This mouthpiece is a correctional mouthpiece, a ported mouthpiece that collapses onto the outer lip and bars and rotates onto the tongue. The port has a tiered design; the base is generously wide with rounded corners, offering virtually the same comfort and tongue relief of a Level 3 mouthpiece, while the top is narrower and has pronounced corners. If the horse is relaxed, the tongue can pass comfortably under the wide opening. When the reins are engaged, the mouthpiece collapses onto the bars and lips and rotates onto the tongue. The pronounced corners of the port apply two points of pressure on the tongue for increased control. The result is a mouthpiece that offers maximum tongue relief for the horse but very good control for the rider. The unique design and the generous tongue relief of the MB 41PB make it the only correctional that can be used long-term, possibly even as a horse’s finishing bit. Sweet iron mouthpiece oxidizes and encourages salivation.
