Myler® Stainless Steel 5 1/2" MBT Shank, MB 36 Mullen Forward Tilt Ported Barrel, Level 2-3. For Western disciplines. 

The MB 36 is a Myler alternative to the traditional mullen, but it has a wide low port that allows the tongue to pass under it comfortably. The port is 1" high and tilted forward at a 45º angle. The design allows just enough room for the horse’s tongue to elevate slightly and swallow, but not high enough to create palate pressure. When the reins are engaged, the MB 36 applies pressure primarily to the bars and lips, but also applies tongue pressure because of the forward tilt. Sweet iron oxidizes and encourages salivation.

Key features:

  • Independent Side Movement™.
  • Sweet iron mouthpiece.
  • Curved mouthpiece does not pinch lips or bars.
  • Copper inlay.


  • This mouthpiece is a step up in tongue relief from Level 2, but because the port is low, it does not offer as much tongue relief as other Level 2-3 mouthpieces with slightly higher ports because the tongue is still somewhat restricted.
  • The MB 36 mouthpiece is similar to the MB 06, except that it is 1/4" higher and the port is tilted forward.
  • The MB 06 mouthpiece will apply less tongue pressure than the MB 36 but additionally offer less tongue relief when the reins are relaxed.
  • For more overall tongue relief and less tongue pressure, see the 43MP.

The MBT shank is a length of flat stainless 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 MBT has the patented Independent Swivel Cheek, where the purchase, mouthpiece and shank all move independently of each other.

The MBT flat shank cheekpiece is an indirect (curb) rein action designed to be used with a curb strap which attaches to the purchase. The MBT uses the combination of fixed cheek and fixed rein to apply pressure to the mouth, chin and poll.
