The Brite-Site Fiber Optic sight system comes in a set" with a front and rear sight. Each sight is built in a CNC machined steel housing providing protection for the fiber cables. The contrasting red front and green rear sight set allows for quick target acquisition and allows you to focus on the front sight easily.
