Viridian RFX44 | 5 MOA Green Dot | Glock MOS

The Viridian RFX44 is a compact closed-emitter reflex sight that provides a single 5 MOA green-dot aiming reference. Designed around a machined 6061 aluminum housing and proprietary green multi-coated optics, the RFX44 prioritizes quick dot acquisition and environmental protection for use on MOS-equipped pistols. Its configuration supports the Aimpoint ACRO footprint while accommodating Glock MOS mounting and includes Instant‑On activation and user-controlled adjustment features.

Use cases include everyday carry and pistol competition where rapid target acquisition and unobstructed sight picture are priorities, and dry-fire or training sessions that benefit from a clear, repeatable dot. The closed-emitter architecture and top-mounted electronics are intended to reduce dot acquisition delay and protect internal components from dust and moisture.
