First Look: Viridian’s RFX45 Closed Emitter Green Dot

Green and enclosed, the RFX45 from Viridian offers another option for an ACRO footprint optic small enough to fit on a pistol.

Made with a 6061 aluminum housing, fully multi-coated lenses, audible and tactile adjustability, INSTANT-ON® activation with memory and auto shut off, and a 50k hour battery life. Plus, the RFX45 is rated for IPX6.

“Eyes see green better, and the RFX45 is a workhorse that comes standard with a lot of technology designed to benefit the shooter,” said Viridian Vice President of Sales, Andy Scott. “The RFX line as a whole has been well received by our customers and consumers because of the features of each optic coupled with green dot technology. As with all Viridian products, we started with the design and put features and specs into these offerings to make them stand out in the market.”

The RFX45, like its predecessors, is backed by Viridian’s Limited Lifetime warranty, has viewing windows maximized (unlimited eye relief) so shooters can get the most benefits around target acquisition and clear fields of view. The closed emitter design ensures shooters will have fast and accurate targeting.
