The Viridian RFX45 closed emitter green dot sight brings precision aiming to your pistol, shotgun, or rifle platform with a compact, rugged design built for shooters who demand reliability in the field or at the range. Unlike traditional open reflex sights, the closed emitter tunnel design accelerates target acquisition by narrowing your visual field and reducing glare—a real advantage in bright sunlight or complex backgrounds. At just 1.73 ounces and built from 6061 aircraft-grade aluminum with hard-coat anodization, this sight adds virtually no weight to your carry gun while withstanding hard use and harsh conditions.

What sets the RFX45 apart is Viridian's proprietary green LED technology. Green reticles are inherently brighter and more visible to the human eye than conventional red dots, especially in daylight, giving you a faster sight picture when seconds matter. The 5 MOA dot is fine enough for precise shot placement at distance yet large enough to acquire quickly at close range. The INSTANT-ON feature wakes the sight automatically when you move it, and the two-minute auto-sleep function preserves your CR2032 battery for up to 50,000 hours of operation—years of hard use on a single cell.

The fully multi-coated optical glass delivers edge-to-edge clarity without distortion, while 10 brightness settings plus 2 night vision modes let you dial in the perfect reticle intensity for any light condition. Audible and tactile windage and elevation adjustments give you precise control with instant feedback. The ACRO footprint makes mounting straightforward on popular pistol slides and tactical rails, and your RFX45 arrives with a low mount included. Rated IPX6 for water resistance and operating across -4°F to 130°F, this sight is engineered to perform when conditions get rough.
