The article, authored by Scott Conditt and published on The Armory Life, explores the performance of Viridian's RFX reflex sights during a live-fire demo in the Arizona desert. Viridian Weapon Technologies, known for its advanced green dot optics, invited Scott to test their sights on various firearms, notably the Springfield Armory Echelon. Scott favorably reviews the VIS's compatibility with reflex sights, which does not require adaptor plates for more than 30 optics. He evaluates five Viridian models — RFX11, RFX15, RFX25, RFX35, and RFX44 — noting their specifications, ease of mounting, size, clarity, and features such as instant-on and auto-off. He emphasizes that Viridian's green optics make it easy to acquire targets on sight, thanks to the human eye's better ability to detect green. Scott concludes by affirming the importance of personal preference in gear selection and praises the Echelon’s versatility in testing various optics.
