Myler Black Steel Seven Shank – Medium Wide Ported Barrel MB 33

The Myler Black Steel Seven Shank MB 33 combines premium materials with balanced performance for refined Western riding. Featuring a black steel “Seven” shank and a sweet-iron mouthpiece with copper inlay, the MB 33 mouthpiece has a generous, wide port (~1½″) allowing the horse’s tongue to pass under the bit with minimal pressure. As one of Myler’s mildest Level 3 bits, it works predominantly off the lips and bars rather than on the tongue or palate—ideal for responsive, trained horses.

Shank Style: Black steel Seven shank (approx. 6¾″ length) offering mild-to-moderate leverage
Mouthpiece: Sweet-iron, copper-inlay MB 33 – generous tongue relief and minimal palate contact
Width: Standard 5″ mouthpiece width (verify fits your horse’s mouth)
Action: Indirect (curb-style) with Independent Side Movement for subtle signals
Use Case: Best for horses accustomed to refined cues and riders seeking soft but clear communication
Care: Rinse and dry after use; lightly oil sweet-iron mouthpiece to prevent rust; inspect shank and rings regularly
