Trijicon 2500021 SRO1-C 1.0 MOA COY

The Trijicon SRO1-C 1.0 MOA red dot sight is a compact, rugged reflex optic built for shooters who demand reliability on the pistol or rifle range. Whether you're running a competition gun, a duty pistol, or an accurate defensive setup, the SRO delivers a clean, uncluttered sight picture with a crisp 1.0 MOA illuminated dot that's easy to acquire and track. Forged from 7075-T6 aircraft-grade aluminum, this sight is engineered to handle the recoil and drops that come with hard use—proven platform, proven durability.

The SRO shines when parallax error matters less than speed and simplicity. Its large, unobstructed field of view keeps you locked on target without tunnel vision, and the wide lens lets you track movement naturally. Eight brightness settings—including two night-vision modes and one super-bright mode—give you total control over illumination, from low-light carry scenarios to bright daylight shooting. The button lock-out mode locks your chosen brightness setting and is ideal for everyday carry, while lock-in mode secures the auto-brightness feature for hunters and competition shooters who want one less thing to think about.

Setup is straightforward: tool-less windage and elevation adjustments mean you can dial in a zero without fumbling for hex keys or special tools. The top-loading CR2032 battery is accessible and swaps in seconds; at setting 4 of 8, expect over three years of continuous runtime. At just 1.6 ounces and 2.2 inches long, the SRO sits low and tight on your slide. The sight shares the same RMR footprint, so it drops into existing Trijicon RMR bases. Note that some modern optics-ready platforms (Glock MOS, Springfield OSP, Walther PDP, H&K VP9 OR) require a separate Trijicon SRO mounting kit. Waterproof to 10 feet, the SRO is ready for any weather you bring to the range or field.

Frequently Asked Questions

Will the SRO1-C fit my Glock MOS or other optics-ready pistol?

The SRO shares the Trijicon RMR mounting footprint and will fit most RMR-ready bases. However, if you're mounting on a Glock MOS, Springfield OSP, Walther PDP, or H&K VP9 Optics Ready platform, you'll need a separate Trijicon SRO mounting kit (model AC32085) to ensure proper fit and function.

Can I use the SRO with iron sights?

Yes. The SRO is parallax-free and designed to coexist with suppressor-height iron sights, so you can maintain backup sight capability or shoot irons-only if the optic fails.

What's the battery life, and how do I change it?

The CR2032 lithium battery lasts over three years of continuous use at mid-brightness (setting 4 of 8). The battery loads from the top, making changes fast and tool-free. Extreme temperatures will affect battery life.

Is the SRO waterproof?

Yes, the SRO is waterproof to 10 feet (3 meters) and built with a forged aluminum housing designed to withstand hard use and environmental exposure.
