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, and require a little more control for show jumping and cross-country, which is provided by the mild gag action of the rings.
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.
The top ring is attached to the cheekpieces to apply poll pressure, resulting in the horse's head lowering, while the half-ring provides leverage, causing a head raising action. When these actions are combined, it results in a gag action. The 2.5 ring, sometimes known as a Universal, is the mildest version of a ring gag because the half-ring softens the leverage on the mouthpiece.
The reins can be attached to this bit in a number of ways to create the desired action: when attached to the big main ring it results in a hanging cheek action with poll pressure, and if attached to the bottom ring it creates a mild gag action.
Please note that the blue will fade with use.
