Reinsman correction bit. 7" cheeks, 5" mouth. 1 5/8" port.
 
"5/16" sweet iron correction with copper stripes. An attractive, well balanced shank with medium plus leverage. Mouthpiece bars are molded so it's comfortable for the horse to carry. Sweet iron and copper create moisture for a softer mouth. The port has slight palage pressure for better headset and more control. It works great on the trail and in the arena. Best used for roping, reining, barrels, and trail riding."
