The MB 03 is the Myler alternative to the traditional French link or lozenge mouthpiece commonly used in snaffle bits with an added copper roller. The MB 03 rotates onto the tongue, applying tongue pressure, but because the mouthpiece is curved, it wraps around the bars and lips instead of pinching.
The barrel in the center applies approximately the same pressure on the tongue as a traditional three-piece mouthpiece, however, the barrel distributes the pressure more kindly and creates Independent Side Movement™. This mouthpiece is made of polished Sweet Iron which naturally oxidizes or rusts. Harmless to horses, it has a sweet taste and promotes salivation.
Notes: The MB 03 is identical to the MB 02 except for a copper roller on the center barrel which can comfort horses that are restless or nervous. For more tongue relief, step up to the MB 04.
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.
