Myler Black Steel 7" Seven Shank, MB 33 Medium Low Ported Barrel, Level 3
The MB 33 is the mildest Myler mouthpiece in terms of tongue pressure. The generously wide port allows room for the tongue to pass almost completely under the bit. Because this mouthpiece does not rotate on to the tongue and the port is wide, it applies little to no tongue pressure, working primarily off the lips and bars. The port on this mouthpiece is only 1 ½" high, so it will apply little to no palate pressure. Because the MB 33 offers such a high degree of tongue relief, the horse that goes well in this mouthpiece has a trustworthy and consistent disposition, and is trained to work off the leg and seat as well as the hands. Sweet iron mouthpiece oxidizes and encourages salivation.

Notes: For a slight increase in tongue pressure, see the MB 43LP or MB 43MP. For same tongue relief without Independent Side Movement, see the MB 16 (Western only). For the same tongue relief and Independent Side Movement, but with a slight degree of collapse, see the MB 05. For more generous tongue relief, see the MB 16PB.
The Black Steel Seven Shank is a length of round black steel in a “7” curve, with a ring purchase and a rein ring. The mouthpiece is fixed to the cheek with a decorative “stack.” The entire shank moves independently of the mouthpiece. The purchase is slightly angled away from the cheek to avoid rubbing.
