The Reinsman Circle R Argentine Snaffle Bit is a timeless classic, used mostly for every day riding and training. As it features more control than a ring bit, the Argentine snaffle bit is often used as a transition when leaving a basic snaffle bit and introducing some low leverage to a young horse. The thinner mouthpiece localizes pressure more, making this snaffle horse bit slightly more aggressive than larger smooth mouthpiece bits. The copper will increases your horse's production of saliva, creating a wet, soft mouth. Copper lasts longer in areas near salt water, but because it is softer than sweet iron, it wears somewhat faster.
