The Trijicon SRO is a specialized reflex sight engineered for pistol slides and compact carbine platforms where a large viewing window and unobstructed sight picture are priorities. The optic uses a simple, precise dot to support rapid target acquisition while preserving sight-picture awareness for both close and intermediate engagements.

Controls provide both manual and automatic LED brightness modes with eight adjustable settings (including two night-vision compatible steps). The sight is powered by a single top-loading CR2032 battery for tool-free replacement without removing the optic, and the forged aluminum housing is waterproof to 10 ft and finished for field durability. No original box or accessories included.
