The MB 04 is similar to the MB 02 in that it will rotate on the tongue and apply tongue pressure, however, it has a small (¼") port that introduces some tongue relief to the horse. The port allows the horse to swallow and move his tongue when he is moving forward and relaxed, which acts as a release or reward. The mouthpiece is curved, and it wraps around the bars and lips instead of pinching. Sweet iron mouthpiece oxidizes and encourages salivation.
Notes: The MB 04 provides an excellent transition from Level One to Level Two. It is suitable for a wide range of horses including green horses, experienced horses entering the Myler System, horses that have been ridden exclusively in a single-jointed mouthpiece, or horses that have not been ridden for a while needing re-schooling.
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.
Size: 6 ¾" shank
Degree of Leverage: Mild to Moderate
