Myler® MBB Black Steel 6 3/4" Medium Shank, MB 06 Mullen with Low Ported Barrel, Level 2-3. For Western disciplines.

The MB 06 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 3/4" high, just enough to allow the horse’s tongue to elevate slightly and swallow, but not high enough to create palate pressure. When the reins are engaged, the 06 applies pressure primarily to the bars and lips. The sweet iron mouthpiece oxidizes and encourages salivation.

Key features:

• Independent Side Movement™.
• Sweet iron mouthpiece.
• Curved mouthpiece does not pinch lips or bars.
• Copper inlay.
• Black shank will discolor over time to an antique brown. 
• Stainless steel dots.

Notes:

• 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 will offer more tongue relief than the MB 06 when the reins are relaxed, but more tongue pressure when the reins are engaged.
• For more overall tongue relief, see MB 43LP.

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.

Action: indirect.

Degree of leverage: moderate.
