Viridian RFX44 Features The Viridian RFX44 places its battery and electronic components at the top of the sight rather than beside the lens resulting in a sleek profile that increases the viewing window while keeping the overall footprint compact. Its closed emitter architecture seals the internal optics against dust moisture and debris addressing one of the most common failure points of traditional open reflex sights. This sealed housing also speeds up dot acquisition helping the shooter find the reticle faster when drawing or transitioning between targets. The 5 MOA green dot reticle built on technology Viridian pioneered two decades ago offers a reticle that the human eye naturally resolves more quickly than a comparable red dot. Machined from 6061 aluminum the RFX44 is built for today s high performance pistols and includes tactile audible adjustments that confirm each click of windage or elevation correction. Auto shut off paired with INSTANT-ON activation preserves battery life while keeping the sight ready the instant the pistol is drawn with up to 30 000 hours of runtime from a single CR1632 battery. The optic ships with a Glock MOS adapter plate and mounting hardware and its native footprint matches both the Aimpoint ACRO and Glock MOS standards for broad slide compatibility. IPX6 environmental sealing and a wide operating temperature range make the RFX44 suited to duty competition and everyday carry use alike.
