The Viridian RFX44 is engineered for rapid target acquisition with a 5 MOA green dot reticle that capitalizes on the human eye's heightened sensitivity to green wavelengths - a technology pioneered by Viridian two decades ago. When compared to red dots, the green reticle and a proprietary specially-designed green multi-coated lens offer unmatched color transmission and crystal-clear visibility.Pushing the boundaries of electro-optic design, the battery and electronic components are situated at the top of the sight, delivering a sleek profile that increases and lowers the viewing window while preserving compactness.The RFX44's closed emitter architecture significantly alleviates one of the prevailing challenges often associated with traditional reflex sights: the delay in dot acquisition. The enclosed housing provides superior protection against environmental elements like dust, moisture, and debris, ensuring consistent performance and long-lasting durability in the toughest conditions.Auto shut off and INSTANT-ON ensures extreme battery life and readiness. Crafted from 6061 aluminum tailored for today's high-performance pistols, the RFX44 also offers tactile and audible adjustments that serve the discerning shooter.
