The Viridian RFX 44 is a compact closed emitter green dot sight built for shooters who demand fast target acquisition without the clutter of traditional reflex optics. This Model 981-0108 pairs a 5 MOA green dot reticle with a closed emitter design that cuts through the delay and environmental interference that plague open-topped sights. If you've ever fumbled with a red dot in bright sunlight or watched dust degrade your sight picture, Viridian's green wavelength technology and sealed housing address both problems—the human eye naturally sees green more clearly than red, and the enclosed design keeps moisture, dust, and debris out of your optics.
The RFX 44's electronics sit atop the housing rather than underneath, a design choice that increases your viewing window while keeping the overall footprint compact enough for modern carry and duty pistols. That means you get a bigger sight picture without ballooning the profile. The 6061 aluminum construction is tough enough for hard use, and the tactile and audible adjustment controls let you dial in your zero with confidence—no fussing, no guessing.
Battery life won't slow you down either. INSTANT-ON activation gets you running immediately, and the auto shut-off preserves juice during the inevitable stretches when your pistol stays holstered. This is the kind of optic that rewards precision shooters—whether you're zeroing at the range, running drills, or carrying for real—because it does one job exceptionally well: it gets you on target fast and keeps you there.

Frequently Asked Questions
What's the difference between the green dot and a standard red dot sight?
The RFX 44's green reticle capitalizes on how the human eye naturally perceives green wavelengths—they appear brighter and crisper than red. Combined with Viridian's proprietary green multi-coated lens, this delivers superior color transmission and visibility, especially in varied lighting conditions.
Why does a closed emitter matter?
A closed housing keeps dust, moisture, and debris out of your optics, protecting internal components and maintaining consistent performance in tough conditions. The enclosed design also speeds up dot acquisition compared to traditional reflex sights.
Will the INSTANT-ON drain my battery?
No. The RFX 44 features INSTANT-ON activation paired with an auto shut-off function, which preserves battery life during periods when the sight is not in use.
Is the RFX 44 compact enough for a carry pistol?
Yes. The top-mounted electronics design streamlines the overall profile while increasing the viewing window, keeping the sight compact enough for modern carry and duty pistols.
