Trijicon® SRO® Reflex Sight 2.5 MOA Red Dot

The Trijicon SRO 2.5 MOA is an open-emitter pistol reflex sight designed to provide a larger field of view and faster dot acquisition. Featuring a forged 7075-T6 aluminum housing, an RMR footprint, and a top-loading CR2032 battery, it is well suited for competition, target shooting, and other applications where speed and precision are equally important.

Large Viewing Window

SRO stands for Specialized Reflex Optic. Compared to the Trijicon RMR, the SRO features a significantly larger, rounded viewing window that makes the aiming dot easier to acquire during the draw, track through recoil, and pick up again during rapid target transitions. The larger window helps maintain visual awareness without sacrificing a compact footprint.

2.5 MOA Red Dot

The crisp 2.5 MOA red dot offers an excellent balance between precision and speed. It obscures less of the target than the 5 MOA version, making it better suited for precise shot placement and longer-distance engagements while remaining fast to acquire during dynamic shooting.

RMR Footprint Compatibility

The SRO uses the industry-standard Trijicon RMR footprint, making it compatible with a wide range of optics-ready slides, mounting plates, and adapters designed for the RMR pattern. Because the SRO's viewing window extends farther forward than an RMR, compatibility with certain holsters should be verified before use.

Top-Loading Battery

The sight is powered by a single CR2032 battery that can be replaced from the top without removing the optic from the slide. This simplifies maintenance and helps preserve the existing zero after battery replacement. Depending on the selected brightness setting and operating conditions, battery life is measured in years.

Brightness Controls and Zeroing

The SRO offers both automatic and manual brightness adjustment with eight brightness settings, including two night vision-compatible levels. Windage and elevation adjustments provide 1 MOA click values with a total adjustment range of 150 MOA, allowing precise zeroing for different firearms and shooting distances.

Forged 7075-T6 Aluminum Housing

The optic features a forged 7075-T6 aluminum housing with a durable black finish. It measures approximately 56 × 33 × 36 mm, weighs approximately 45 g, and is waterproof to 3 m. The robust construction is designed to withstand the repeated cycling forces of slide-mounted pistol use.

Designed for Competitive Shooting

Introduced as a complement to the Trijicon RMR, the SRO prioritizes rapid target acquisition and improved sight tracking while retaining the proven RMR mounting footprint. Its larger viewing window has made it a popular choice for competition shooters and anyone seeking faster visual feedback during rapid strings of fire.
