Trijicon SRO 5 MOA Red Dot Reflex Sight, Black

Description

Trijicon SRO 5 MOA Red Dot Reflex Sight, Black

The Trijicon SRO 5 MOA red dot sight combines a prominent aiming point with a wide viewing window and a black anodized housing.

The 5 MOA red dot is the largest aiming point in the red-dot SRO range. Its more prominent appearance suits buyers who prefer a bolder reference to the smaller 1 MOA and 2.5 MOA dots. The trade-off is greater coverage of a small aiming mark, so the choice comes down to the sight picture you prefer.

The SRO3-C-2500003 optic combines that larger dot with a black anodized housing and a non-magnifying view. Its 0.98 x 0.89-inch window provides a broad view through the sight without adding a circle or secondary reticle. The larger dot does not change the optic’s size or mounting footprint.

Brightness Control and Battery Access

Side-mounted buttons provide eight manual brightness settings, including two night-vision-compatible levels and a super-bright setting. Automatic mode responds to ambient light. Lock-In mode holds your selected brightness, while Lock-Out mode keeps the optic in automatic operation and prevents accidental changes with the buttons.

The top-loading compartment lets you replace the CR2032 battery without removing the optic from its mount. Trijicon rates red-dot SRO battery life at over three years of continuous use at setting 4 of 8 and 70 degrees Fahrenheit (21 degrees Celsius). Higher brightness settings and extreme temperatures can shorten that runtime.

Construction and Mounting

The housing is made from forged 7075-T6 aluminum and uses an open-emitter design. The RMR mounting footprint provides a choice of compatible mounts and adapter plates, but the SRO optic’s larger body still needs appropriate clearance. A rail mount or platform-specific adapter plate is not included.

Confirm SRO compatibility with your exact platform and holster before purchasing. Trijicon advises against installations where the front of the optic overhangs the chamber or breech face, because that can interfere with ejection. The RMRcc footprint is different from the standard RMR pattern used by this optic.
