Myler HBT Shank Bit with MB 04 Comfort Snaffle Mouthpiece - Sweet Iron & Copper - Multiple Sizes

Refine Your Communication with the Myler MBT Shank 04

If your horse has mastered the basics in a snaffle but is ready for a more finished feel without the harshness of a traditional curb, the Myler MBT Shank 04 is the tool you have been looking for. Designed for the Level 2 horse, this bit bridges the gap between direct and indirect reining, offering a 1/4 inch low port that provides tongue relief while still giving you the control you need on the trail or in the ranch arena.

What sets the Myler MBT Shank 04 apart is its ability to communicate clearly without the nutcracker pinch. The stainless steel MBT shank provides mild-to-moderate leverage, making it a favorite for western riders who value a soft, responsive mouth and a horse that stays relaxed under pressure. From our barn to yours, this bit is built for the long haul.

Why Riders Trust the MB 04 Mouthpiece

• Isolate cues with Independent Side Movement: The MB 04 mouthpiece allows you to lift one shoulder at a time, providing the lateral control usually only found in snaffles.
• Encourage a wet mouth with Sweet Iron: The mouthpiece is crafted from sweet iron with copper inlays, which naturally oxidizes to create a sweet taste that promotes salivation and relaxation.
• Protect the bars and tongue: The 1/4 inch low port offers mild tongue relief and rotates onto the tongue to apply pressure only when needed, preventing constant discomfort.
• Enjoy smooth, rub-free action: The MBT Shank features a swivel cheek design that prevents pinching at the corners of the mouth while offering a stable, flat-shank feel.

Best For

Western trail and ranch riders looking for a gentle transition from a snaffle to a curb bit that offers refined lateral cues and tongue relief.

Frequently Asked Questions

Q: How do I choose the right size for a Myler bit?

Myler bits, including the Myler MBT Shank 04, are designed to run slightly large—usually about 1/8 inch to 1/4 inch wider than their advertised size. You want to see about 1/8 inch of space on each side of the horse's mouth for a perfect fit.

Q: Why is the mouthpiece turning brown or rusty?

Don not worry—that is intentional! The sweet iron material is designed to oxidize, which creates the sweet taste horses love. This encourages salivation and a more receptive, softer mouth.

Q: Is this bit legal for Western Pleasure or Dressage?

The MBT Shank 04 is a Western-style curb bit and is generally not legal for Dressage. While widely used in Western Pleasure and trail classes, always check your specific association rulebook for shank length and mouthpiece requirements.
