This bit has our absolute favorite mouth from Myler. The comfort snaffle mouth offers great anatomical support, ample tongue relief to make this even more supportive of your horse. This 5″ Myler Western D Comfort Snaffle (MB 03) is in good used condition, with hooks that give the rider mild leverage options. The mouth is made from sweet iron, which rusts with use to offer a pleasant taste for your horse. This one is just starting to rust. Per Myler:
The MB 03 is the Myler alternative to the traditional French link or lozenge mouthpiece commonly used in snaffle bits with an added copper roller. The MB 03 rotates onto the tongue, applying tongue pressure, but because the mouthpiece is curved, it wraps around the bars and lips instead of pinching. The barrel in the center applies approximately the same pressure on the tongue as a traditional three-piece mouthpiece, however, the barrel distributes the pressure more kindly and creates Independent Side Movement™. Sweet iron mouthpiece oxidizes and encourages salivation.
