The MB 16 is similar to the MB 33 but without the Independent Side Movement. The generously wide port allows room for the horse’s tongue to pass under the bit. Because this mouthpiece is very wide, it applies little to no tongue pressure, working primarily off the bars, chin and poll. This mouthpiece does not offer Independent Side Movement, making it suitable for competing in sports where excessive rein movement is undesirable (reining, Western pleasure). The port on this mouthpiece is 1 ⅝" high, so it will apply little or no palate pressure. Sweet iron mouthpiece oxidizes and encourages salivation.
NO Independent Side Movement
Sweet Iron mouthpiece
Notes: For a similar mouthpiece with Independent Side Movement, see the MB 33 or MB 05. For a slight increase in tongue pressure, see the 43LP.
The 7" Flat Shank is stainless steel and curved slightly back towards the horse, with a flat-top purchase and a rein ring. The mouthpiece has a fixed attachment. The Flat Shank has the patented Independent Swivel Cheek, where the purchase, mouthpiece and shank all move independently of each other. The purchase is slightly angled away from the cheek to avoid rubbing. It has an indirect (curb) rein action designed to be used with a curb strap which attaches to the purchase. The flat shank uses the combination of the fixed cheek and fixed rein to apply pressure to the mouth, chin and poll.
