Trijicon SRO Features The Trijicon SRO uses a wide field of view housing design that lets shooters acquire the dot quickly during rapid target transitions a real advantage over narrower-window reflex sights in competitive and defensive pistol shooting. Manual and automatic LED brightness modes adjust the dot intensity to ambient light so the reticle stays visible from a dim indoor bay to bright outdoor sun without the shooter constantly re-adjusting settings. A rated 3-year battery life on a single CR2032 cell means the sight is ready to perform without frequent battery swaps and the electronics share the same proven design lineage as the Trijicon RMR. At 2.20 inches long 1.40 inches tall and 1.30 inches wide weighing just 1.60 ounces the SRO adds minimal bulk to a slide-mounted pistol. Forged from 7075 T-6 aircraft grade aluminum the SRO housing is significantly more durable than reflex sights built from cast or lower-grade materials and it has been tested to survive the drops and impacts typical of pistol mounted duty use. This forged construction protects the internal lenses and electronics from the shock of dry-fire practice holster re-holstering and range handling over years of service. Finished in Coyote Brown to complement tan and FDE pistol builds the SRO is a durable field-tested reflex sight for shooters who demand reliability from their carry or competition optic.
