Viridian 9810058 RFX45 Closed Emitter Green Dot Sight Black | 24 x 15.5mm 5 MOA Green Dot$349.00
Availability: In Stock
The Viridian RFX45 green dot sight brings a closed-emitter reflex design to shooters who demand fast target acquisition and reliable performance in the field. Unlike open-style red dot sights, the RFX45's tunnel configuration lets your eye naturally center on the reticle faster—a real advantage whether you're on the range, hunting, or training for defensive use. Viridian's choice of a bright green LED over the standard red delivers superior visibility across varied lighting conditions, a hallmark of the brand's optics lineup. Built from 6061 aircraft-grade aluminum and hardcoat anodized for durability, this compact sight weighs just 1.73 ounces and fits the ACRO footprint, making it equally at home on a pistol slide or a lightweight carbine.
The RFX45 is engineered for real-world shooting. Its INSTANT-ON activation fires the sight the moment you move it, eliminating the fumbling of manual power switches; when you set it down for two minutes, it automatically sleeps to conserve battery life. A single CR2032 battery lasts over 50,000 hours—that's years of occasional use or extended range sessions. The 5 MOA dot is clean and fast to pick up, and fully multi-coated glass delivers optical clarity without distortion. You get 10 brightness settings, plus 8 additional levels calibrated for night vision devices, alongside 90 MOA of total adjustment to dial in your zero.
This is a purpose-built sight for shooters who value simplicity and visibility. No frills, no gimmicks—just a well-made green dot that works when you need it.

The RFX45 uses the ACRO footprint and is compatible with ACRO-pattern optics mounts found on many modern pistols and carbines. The product ships with adapters and mounts to ensure compatibility with your platform; verify your specific firearm's mounting standard before purchase.
A closed-emitter design confines the LED within a tunnel, which naturally guides your eye to the center of the reticle faster than an open-frame sight. This can result in quicker target acquisition, especially under stress. The green LED itself offers better brightness and visibility in daylight and mixed lighting compared to traditional red dots.
The RFX45 runs on a single CR2032 battery and delivers over 50,000 hours of runtime. That translates to years of regular use. The INSTANT-ON activation with automatic 2-minute sleep mode also helps stretch battery life by powering down when the sight isn't being moved.
Yes. The RFX45 includes 8 brightness settings optimized for use with night vision equipment, in addition to 10 standard daylight levels, giving you flexibility across different shooting scenarios and conditions.
