The McHardy mouthpiece from Bombers Bits is a hybrid between the Happy Tongue and Buster Roller. It is ported to allow space for the tongue, relieving pressure in this area and promoting relaxation, while the 40mm central roller encourages the horse to play with the bit and deters leaning.

This bit is often suitable for horses with large or sensitive tongues that tend to drop their head and lean on the bit.

The blue sweet iron mouthpiece oxidises easily, creating a warm, sweet taste in the horse's mouth. This encourages the horse to salivate, gently mouth the bit and relax his jaw, and can help horses who have difficulty accepting conventional metal bits.
