Viridian RFX45 | 5 MOA Green Dot | ACRO/RMR Adapter

The Viridian RFX45 is a closed-emitter reflex sight built around a highly visible 5 MOA green dot and an ACRO footprint with an included RMR adapter. The sight uses a sealed emitter to protect the optic, a machined 6061 aluminum housing with hard coat anodization for durability, and INSTANT‑ON activation with memory and auto shutoff for extended battery life. It is designed for rapid target acquisition on compact pistols and for use in action pistol competition where a rugged, low-profile sight is required.
