Myler Black Steel 6 3/4" MBB Medium Shank, MB 16PB Wide Ported Barrel, Level 3
The MB 16PB has a generously wide and moderately high port that allows plenty of room for the horse’s tongue to pass under the bit, more so than the MB 33. Although the port is 1 ⅞", its generous width makes the mouthpiece sit very low in the mouth, minimizing the likelihood of any palate pressure. Sweet iron mouthpiece oxidizes and encourages salivation.

Sweet Iron mouthpiece
Black shank will discolor over time to antique brown
Stainless steel dots
Notes: For slightly less tongue relief, see the MB 33 or MB 05. For the same tongue relief without Independent Side Movement, see the MB 16.
The MBB shank is a length of flat black steel curved slightly back towards the horse, with a teardrop purchase and a rein ring. The mouthpiece has a fixed attachment to the cheek with a decorative “stack.” The shank is decorated with stainless steel dots. The purchase is angled slightly away from the cheek to avoid rubbing. The black steel will discolor over time to an antique brown.
The MBB flat shank is an indirect (curb) rein action designed to be used with a curb strap which attaches to the purchase. This shank uses the combination of fixed cheek and fixed rein to apply pressure to the mouth, chin and poll.
