Viridian RFX45 Closed Emitter Green Dot 5 MOA 1x 24x15.5mm - ACRO/Picatinny High 1/3 Cowitness Mount

The Viridian RFX45 is a closed-emitter green dot reflex sight engineered for both optics-ready pistols and rifles. It is built on a rugged machined 6061 aluminum housing finished in black anodize, and it ships with a high 1/3 cowitness Picatinny mount for fast co-witnessed aiming alongside iron sights. The optic uses an ACRO-compatible footprint so it also drops directly onto ACRO-pattern pistol slides.

Through a fully multi-coated 24 mm x 15.5 mm lens window, the RFX45 projects a crisp 5 MOA green dot at 1x magnification with unlimited eye relief, giving the shooter an unobstructed sight picture for rapid target acquisition in varied lighting. Windage and elevation are tuned with audible and tactile 1 MOA per-click adjusters, and the sealed housing is rated waterproof for dependable field use.

A single CR2032 battery powers the RFX45 for up to 50,000 hours of run time. Viridian's INSTANT-ON activation wakes the optic the moment the host firearm is moved, resumes the last-used brightness setting, and then shuts off automatically when the gun is holstered or set down. Measuring just 1.90" long and 1.73 oz, this is a compact, low-profile aiming solution ready to mount right out of the box.
