This Bombers Blue 2.5 Ring Gag bit combines a lightweight ported mouthpiece with a 2.5 ring gag, which offers a mild gag action.
The lightweight rubber nylon compound mouthpiece is ported for tongue relief. This reduces tongue pressure, while applying pressure to the bars of the mouth. This bit may be suitable for horses with large tongues, who find straight bar bits uncomfortable.
2.5 Ring Gag
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.
