Bombers Polo Big Ring Gag Buster Roller

A gag works by lifting the bit in the mouth in order to encourage the head to be raised. Often used on strong horses that like to lower their heads in order to escape the action of the bit in the mouth and get very strong.

When pressure is applied to the rein, the bit is lifted in the mouth and poll pressure is applied. The bit also rotates slightly in the mouth putting more pressure on the tongue and bars.

The Buster Roller link is shortened which increases bar and tongue pressure making this mouthpiece sharper than conventional link bits. The increased pressure on the bar will lift the head and the roller will increase pressure on the tongue bringing the chin in. Best suited for a horse with a low head carriage and which leans on the bit.

To be correctly used, it must be used with two reins one on the gag rein and one on the bit, only bringing the gag rein into play when needed, although most people ride on the gag rein only.
