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.
The 6" stainless steel 3-ring combination bit is a hybrid of a ring
bit, shank bit, and hackamore and uses five different pressure points to
disperse rein pressure. Because the noseband and chin strap are
connected through the purchase, when the reins are engaged, the horse
first feels nose, chin and poll pressure before he feels the mouthpiece.
The mouthpiece can slide 1" before reaching a stop, where it will then
engage and apply pressure. The purpose is to give the horse an
opportunity to respond to the rider’s rein signals before applying
mouthpiece pressure. The combination bit has Independent Swivel Cheek
and the purchase is slightly angled away from the cheek to prevent
rubbing. The noseband is flat leather with knotted cord on either side
and the chin strap is synthetic to avoid stretching over time. Tie down
built into noseband.
