Stainless Steel 5" HBT Shank with Sweet Iron Mullen Barrel Low Port (MB 06) Copper Inlay Mouth. This mouthpiece is made of polished Sweet Iron which naturally oxidizes. About the mouthpiece: the 06 mouthpiece is a Myler alternative to the traditional mullen mouthpiece. Like the traditional mullen the 06 is also a solid curved bar that sits across the bars of the horse's mouth, but it has a wide low port that allows the tongue to pass under the bit comfortably. The port is ¼" high, just enough to allow the tongue to elevate slightly and swallow, but not high enough for palate pressure. Because the port is low, the 06 doesn’t o?er as much tongue relief as other Level Two-Tree mouthpieces with slightly higher ports because the tongue is still somewhat restricted. The curved mouthpiece wraps the horse’s mouth, allowing more space for the tongue under the bit. When the reins are engaged, the 06 applies pressure primarily to the bars and lip. This mouthpiece also has Independent Side Movement . This mouthpiece is a step up in tongue relief from Level Two. The 36 mouth piece o?ers more tongue relief when the reins are relaxed, but more tongue pressure when the reins are engaged. For more tongue relief, see the 43LP.

Degree of leverage is mild. Patented swivel purchase moves independently of both the mouthpiece and shank so that it doesn’t dig into the horse’s cheek when neck reining. Independent Side Movement. Level 2-3.
