Here is one of our favorite mouth pieces! In good used condition from Reinsman #349! Jr Cowhorse bits are some of our most popular selling bits. This one has a thicker, sweet iron mouth, in 3/8″ diameter, smooth, with a contour mouth and dog bone center with large copper roller. Smaller rings than some to limit gag action, slightly shorter shanks at 5.5″. Dog bone center helps limit the nutcracker effect of snaffle joints.
