Trijicon Fiber Sights are purposely engineered to bring the absolute brightest aiming point while retaining strength and maintaining a refined sight picture. A bright front post fiber combined with a subdued rear sight promotes acquisition of front sight and target. Using leading edge fiber technology and Trijicon's legendary rugged metal construction, this fiber sight maximizes retention and durability. Rounded edges of rear sight reduce snag points for improved comfort while carrying. Trijicon Fiber Sights come from the factory with a .060" red fiber pre-installed on the front sight, and an extra red and green fiber replacement in the package. Whether carrying or competing, these bright, thin sights create the perfect aiming point for fast, accurate rounds on target.
