The Diamond R 6 in. Argentine Forward Bit Set with Copper Inlay Roller gives a soft, even pressure across the tongue, bars, and lists. The center barrel has limited movement to prevent the bit from scissoring down into the tongue or up into the palate. The copper roller provides some movement helping to pacify the nervous horse. Argentine cheeks offer versatility, hooking reins to the middle rings offers direct rein pressure or moving reins down to the teardrop rings and adding a curb chain provides leverage.
