The Viridian RFX45 Closed Emitter Green Dot Reflex Sight, ACRO compatible with a Glock MOS adapter included (Viridian part no. 9810051), packs industry-leading features into a sight built around a rock-solid, machined 6061 aluminum housing. A closed-emitter design shields the internal light source from dirt, debris, and moisture better than an open-emitter sight, while fully multi-coated lenses, audible and tactile adjustment clicks, and a 50,000-hour battery life round out the package. Viridian pioneered green laser pistol sights nearly two decades ago, and the RFX line, launched in 2021, carries that legacy forward with exclusively highly visible green LED reticles.
