Myler Hbt Shank Low Port Snaffle Mb04 - Test Ride Bit

Offering a balanced step up from Level 1 designs, the Myler MB04 Low Port Comfort Curb Bit provides tongue relief and mild leverage, making it ideal for green horses or those needing a refined introduction to curb pressure. The MB04 mouthpiece features a wide barrel with a low 1/4" port that rotates on the tongue, allowing more freedom and encouraging forward motion. Made with sweet iron and copper inlay to promote salivation, this bit includes Myler’s patented Independent Side Movement for clear, lateral rein cues. The shorter shank offers mild curb action and is well-suited for trail riding or everyday Western training.
