Fiber-Optic Pro delivers a sight picture that is fast and accurate for competitive and recreational shooters. A patented light reflector focuses available light from all angles onto the fiber for a brighter glow, even in low light conditions. Most Fiber-Optic sights gather light from the top and somewhat from the sides. A patented light reflector in Truglo Fiber-Optic Pro sights redirects light onto the entire surface area of the fiber. Traditionally, the best way to make a Fiber-Optic brighter has been to make it longer, however, this decreases the sight radius. The reflector design allows light exposure on 360 degree of the fiber making it brighter without needing to make the fiber longer.
