Viridian 9810056 RFX25 Green Dot Reflex Sight Black | 20 x 28mm 3 MOA Green Dot Reticle

The Viridian RFX25 green dot reflex sight brings rapid target acquisition and reliable performance to optics-ready compact and full-size pistols. This compact reflex sight features a crisp 3 MOA green dot housed in a lightweight 6061-T6 aluminum body, purpose-built for shooters who demand speed and clarity in any lighting condition. Whether you're training at the range, carrying for defense, or competing, the RFX25's instant-on activation and automated brightness adjustment keep you ready without fumbling with controls.

The 20×28mm viewing window gives you a clean sight picture while maintaining the minimal profile that pistol shooters expect. Eight visible brightness levels plus two dedicated night vision settings mean the green dot stays visible and usable from predawn hunts through low-light home defense scenarios. With over 30,000 hours of battery life on a standard CR2032, you'll go months between swaps—and the sight powers down automatically after 2 minutes of inactivity to preserve every bit of runtime.

Built on the Docter mounting footprint and compatible with Picatinny rails via the included adapter, the RFX25 fits most modern optics-ready pistols without proprietary guesswork. The whole package weighs just 0.75 ounces and is rated IPX6 waterproof, so it handles the range, the field, and everything in between. Viridian backs it with a lifetime limited warranty, and you get a complete accessory kit—battery, Picatinny mount, wrench set, and mounting hardware—right out of the box.

Frequently Asked Questions

What pistols does the RFX25 mount on?

The RFX25 is designed for optics-ready compact and full-size pistols that use the Docter mounting footprint. It also ships with a Picatinny mount adapter, expanding compatibility to most modern optics-ready platforms. Check your specific pistol's manual to confirm it accepts a Docter or Picatinny sight mount.

How long does the battery last, and what type is it?

The RFX25 runs on a standard CR2032 battery with over 30,000 hours of runtime at middle brightness settings. The sight automatically powers down after 2 minutes of inactivity, which further extends battery life between replacements.

What comes in the box?

You get the RFX25 sight itself, a CR2032 battery, a Picatinny mount adapter, a wrench set for tool-free installation, a cleaning cloth, a quick start guide, and registration materials for warranty and exclusive promotions.

Can the RFX25 handle wet conditions and rough use?

Yes. The RFX25 is rated IPX6 waterproof and has been tested in harsh field conditions. Its 6061-T6 aluminum body is built to withstand regular use, and the sealed design keeps water and debris out of the optics.
