Myler Lynn McKenzie Signature Series Stainless Steel MMB 7 1/2" Long Shank, MB 43LP Narrow Low Ported Barrel, Level 2-3
The MB 43LP does not rotate on to the tongue, but instead sits solidly across the bars and lips of the horse’s mouth. The port is narrower than a Level 3 mouthpiece, but still offers room for the horse’s tongue to pass under the bit. Because the port is narrow, when the reins are engaged, the horse will feel a slight pressure on the outside edges of the tongue — a gentle reminder rather than a strong reprimand. The port on this mouthpiece is only 1 ¼" high, so it will apply little to no palate pressure. It is the mildest of the Level 2-3 mouthpieces in terms of tongue pressure, just one step below a Level 3 mouthpiece. Sweet iron mouthpiece oxidizes and encourages salivation.
- Independent Side Movement

Note: For a shorter shank and lower port, see the MMB Medium Shank with MB 06.
The MMB shank is an indirect (curb) rein action designed to be used with the curb chain which is attached to the purchase. The MMB shank uses the combination of the fixed cheek and fixed rein to apply pressure to the mouth, chin and poll. The MMB’s innovation is the sliding action of the mouthpiece. When the reins are engaged, the mouthpiece moves, giving the horse the opportunity to respond to the lightest signal before the mouthpiece hits the stop. The distance the mouthpiece can travel between the stops means that this cheekpiece will not apply very much downward pressure. The design of the mouthpiece attachment does not allow the mouthpiece to slide as readily along the shank giving it a more solid feel than the HBG. The patented Neil Merrill purchase plate disperses pressure evenly against the horse’s face.
