Hiviz sights are machined from solid steel and feature fiber optic inserts for increased visibility. The steel portion of the sight has a square profile to decrease the time to acquire the sight picture. The fiber optic LitePipe is recessed slightly to reduce the halo effect experienced with some fiber optic sight. The light pipe is protected by a clear resin overmold, making the sight more durable for rugged use like duty or competition. Fiber optic LitePipes are not interchangeable on overmolded sights.
Sights for models with pinned front are not pre-drilled for the retaining pin. Gunsmith installation is recommended.
