Myler Black Steel Seven Shank SI Low Port Copper Roller Comfort Snaffle MB 04 - Test Ride Bit

Combining clarity and comfort, the Myler MB04 Low Port Comfort Seven Shank Curb Bit with Copper Roller offers enhanced tongue relief and a touch of play to keep the horse soft in the mouth. The wide barrel mouthpiece features a 1/4" low port and a center copper roller that encourages salivation, focus, and suppleness. This Level 2 bit provides mild to moderate leverage with indirect action, ideal for horses progressing beyond snaffle-style bits or entering re-schooling. The sweet iron construction oxidizes naturally for a taste horses accept, while the decorative Seven Shank offers stylish function with independent movement between the shank and mouthpiece.
