Holosun SCRS GR 2 Green Dot Sight - 1x20mm, 2 MOA, Black Anodized

The Holosun SCRS GR 2 green dot sight is a compact 1x20mm optic purpose-built for rifle shooters who want a lightweight sight that doesn't eat battery life. This is Holosun's solar-powered rifle dot—the SCRS platform—engineered around a straightforward mission: clip it to your rifle, dial it in, and trust it to work whether you're shooting at the range or hunting. The green reticle is sharper and easier on the eyes for most shooters compared to red in bright conditions, and the 2 MOA dot strikes a practical balance between precision and speed across typical hunting and tactical distances.

The sight runs on multi-directional solar cells paired with a battery backup, so you're not constantly swapping or carrying spares. That said, Holosun built in both Automatic and Manual modes, giving you flexibility: let the ambient light sensor handle intensity for you, or take the wheel yourself when you need consistency in shadow or low-light work. The 7075 aluminum tube is tough and lightweight, and the black anodized finish handles recoil and weather like any quality optic should.

What sets this Holosun apart is the 509T footprint. If you already run offset mounts or plan to pair this with magnified glass behind it, the 509T pattern gives you proven compatibility with a wide third-party ecosystem. That means you're not locked into Holosun's mounting ecosystem—you can adapt the sight to your existing rig.

Frequently Asked Questions

Is the Holosun SCRS GR 2 compatible with my current offset mounts?

The SCRS GR 2 uses the 509T footprint, which is a common standard for offset mounts made by Holosun and many third-party manufacturers. Check that your mount is 509T-compatible; if it is, the sight will mount directly without adapters.

Can I use this sight with a magnified scope behind it?

The 509T footprint is designed to pair with primary magnified optics when mounted on an offset rail. Many shooters run this sight as a co-witness or backup to a larger scope. Verify your rail height and mount ring clearance for your setup.

How does the solar charging work?

The SCRS features multi-directional light sensors that capture ambient light and power the reticle. In bright daylight, the sight charges while in use. It also contains a battery backup, so it will continue to function indoors, at dusk, and in low-light conditions without constant battery replacement.

What's the difference between green and red dot on this sight?

Green reticles are generally brighter and crisper to the human eye in daylight and high-contrast conditions, which can reduce eye strain for some shooters. Red dots are traditional and equally capable, but many shooters prefer green for hunting and outdoor shooting. The SCRS GR 2 is the green-dot variant; Holosun also makes red-dot versions if you prefer that color.
