Myler Stainless Steel 7" Flat Shank, MB 04 Low Port Comfort Snaffle, Level 2
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.
