The Trijicon Specialized Reflex Optic (SRO) 1.0 MOA Adjustable LED red dot is best suited for use on a rifle or target pistol application or in applications where increased accuracy at distance is needed. The wide field of view and clean, crisp dot makes it easy for users to find and track the dot in both target and competitive shooting applications, helping improve shooting accuracy and speed. Every SRO features both manual and automatic LED brightness modes and a 3-year battery life. The SRO is designed to survive the rigors of slide ride pistols and is engineered for hard use. It shares a similar electronics design with the proven Trijicon RMR. Like the RMR the SRO is forged from 7075, T-6 aircraft grade aluminum, making it much more durable than conventional red dot sights. This forged housing protects the lenses and electronics, and it has been tested to survive typical pistol mounted drops.
