The Trijicon SRO Specialized Reflex Optic (2500003) is a large-window open reflex pistol sight forged from 7075-T6 aluminum on the RMR footprint, delivering a 5 MOA red dot through a 0.98 x 0.89 inch tempered glass window with 8 brightness settings, automatic illumination, and over three years of CR2032 battery life on a top-load battery tray. Designed for competitive pistol shooters and target shooters who want a large-window 5 MOA red dot sight for RMR-footprint pistols where speed and dot recovery are the primary performance drivers, the 2500003 brings the same forged aluminum construction and electronics platform as the proven Trijicon RMR in a wider, taller window format purpose-built for fast presentation shooting.

Special Features
- The top-load CR2032 battery compartment allows a battery swap without removing the sight from the slide, keeping your mount torque and zero intact between every battery change without a re-zero session.
- The 0.98 x 0.89 inch window is significantly larger and more circular in shape than the RMR window, giving your eye a wider, less obstructed sight picture that makes the 5 MOA dot faster to find and easier to track through follow-up shots.
- The shared electronics design with the Trijicon RMR means the SRO runs on the same proven digital illumination platform that has accumulated millions of rounds of service on duty and competition pistols worldwide.
- Lock-In and Lock-Out modes prevent accidental brightness changes from holster pressure, gear contact, or incidental button presses during carry, draw, and reholster without requiring manual activation before use.
Practical Benefits
- The RMR footprint mounts to any slide milled for a Trijicon RMR, covering factory MOS pistols, aftermarket milled slides, and existing RMR mounts on Glock, Sig, Smith and Wesson, CZ, and other full-size and compact platforms without an adapter.
- The 5 MOA dot size delivers a bold, fast-recovery aiming point that your eye finds instantly on a rapid draw and tracks through strings of fire without hunting for a smaller dot after each shot, which makes the SRO a natural fit for competition divisions where speed drives score.
- Your 2500003 gives you Trijicon's forged aluminum construction and proven electronics platform in a wide-window, large-dot format that prioritizes dot acquisition speed and recovery over precision dot size on every stage and target you engage.
The Trijicon SRO Specialized Reflex Optic (2500003) with its 5 MOA red dot and large circular window is a proven platform for competitive pistol shooters and target shooters who demand the fastest possible dot acquisition and recovery on an RMR-footprint slide built for hard use.
