Holosun SCRS RD 2 Red Dot Sight - 1x20MM, 2 MOA, Black Anodized

The Holosun SCRS RD 2 is a compact 20mm red dot sight built for shooters who want reliability without the bulk. This ultra-compact optic brings Holosun's proven Solar Charging Rifle Sight (SCRS) technology to a 2 MOA dot configuration—ideal for riflemen running carbines, precision builds, or setups where space and weight matter. Whether you're zeroing a hunting rifle, running drills at the range, or setting up a duty weapon, the SCRS RD 2 delivers the speed and simplicity of a true reflex sight in a platform that plays well with modern rifle ergonomics.

The SCRS RD 2 is housed in a 7075 aluminum body, anodized black, and rides on Holosun's 509T footprint—the same interface trusted by offset mount manufacturers worldwide. That footprint compatibility means you're not locked into one mounting ecosystem; you can integrate this sight with third-party RDS mounts and adapt it to your setup. The 2 MOA reticle is precise enough for accurate shot placement at distance yet fast enough to pick up targets close in, making it a genuine all-range tool rather than a compromise dot.

Holosun's dual-mode operation gives you flexibility in the field. Automatic Mode reads ambient light through multi-directional light sensors and sets your reticle brightness automatically—no thinking, just shooting. If you prefer hands-on control, Manual Mode lets you dial in dot intensity yourself. The black anodized finish resists corrosion and reflects the kind of durability you expect from a sight that's designed to stay on your rifle for years of real use.

Frequently Asked Questions

Is the Holosun SCRS RD 2 compatible with offset mounts?

Yes. The SCRS RD 2 uses Holosun's 509T footprint, which is the standard interface for third-party offset red dot sight mounts. This gives you flexibility to configure your optics setup with tools from multiple manufacturers.

What's the difference between Automatic and Manual Mode?

Automatic Mode uses multi-directional light sensors to detect ambient brightness and adjust your reticle intensity without user input—set it and forget it in changing light. Manual Mode puts that control in your hands so you can dial brightness to your preference regardless of lighting conditions.

What does the solar charging feature mean?

The SCRS platform integrates solar charging capability, allowing the sight to harness natural and artificial light to maintain power. This is part of Holosun's SCRS technology suite and supplements battery operation.

What size mount does this red dot need?

The SCRS RD 2 is a 20mm tube sight and uses the 509T footprint for mounting. You'll need a mount designed for 509T interface or a 20mm ring mount with 509T capability to install it on your rifle.
