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.
