Viridian 9810051 RFX45 Green Dot Reflex Sight Black | 24 x 15.5mm 5 MOA Green Dot Reticle$349.00
Availability: In Stock
The Viridian RFX45 green dot reflex sight brings the visibility advantage Viridian pioneered in laser sights to a fast-acquiring closed-emitter design. This compact, pistol-ready optic pairs a bright 5 MOA green reticle with a tunnel-style housing that cuts visual clutter and gets your sight picture on target quicker than open reflex designs. Built from machined 6061 aluminum with hard-coat anodization, it's rugged enough for duty, competition, or serious carry without adding weight—just 1.73 ounces. The green LED outshines red dots in daylight and low-light conditions, giving you an edge whether you're at the range, in a defensive scenario, or hunting in variable light.
Viridian engineered the RFX45 to work the way shooters actually carry and deploy. INSTANT-ON activation wakes the sight the moment you move, eliminating the fumble of manual switches. Its auto-sleep feature powers down after 2 minutes of stillness, stretching battery life to an impressive 50,000+ hours on a single CR2032 cell—meaning you can install it and forget about it for years. Ten brightness settings plus two dedicated night vision modes adapt to any lighting condition. Audible and tactile adjustments let you dial in your point of aim with confidence, backed by 90 MOA of total adjustment range.
The RFX45 mounts on the ACRO footprint, giving you access to a wide ecosystem of slides, carriers, and mounting solutions. Its fully multi-coated lens delivers optical clarity without distortion, and IPX6 weatherproofing keeps it running from -4°F to 130°F. Whether you're running it on a compact carry gun, a duty weapon, or an AR pistol, this is a sight built for serious shooters who demand reliability and visibility without compromise.

The RFX45 uses the ACRO mounting footprint, which is the industry standard for modern pistol and AR-platform optics. You can mount it directly on ACRO-compatible slides, or use ACRO adapter plates for other slide patterns. Check your gun's manual or ask us about compatibility for your specific model.
The RFX45 runs up to 50,000+ hours on a single CR2032 battery—roughly 5+ years of continuous use. The auto-sleep feature powers down the sight after 2 minutes of inactivity, extending real-world battery life significantly since the sight spends most of its time holstered or on a shelf.
Viridian's green LED is brighter and more visible than red across a wider range of lighting conditions, especially in daylight and low-light scenarios. Green reticles naturally stand out to the human eye. Combined with the closed-emitter design, the green dot helps you lock onto your target faster.
Yes. The sight includes two dedicated night vision modes, so it works seamlessly whether you're shooting with or without NV devices. The standard brightness modes work in daylight and low-light pistol shooting.
