Viridian RFX44 Compact Reflex Sight | 5 MOA Green | 9810107

The Viridian RFX44 is a compact closed-emitter reflex sight built for fast, consistent dot acquisition. It uses a 5 MOA green-dot reticle paired with a proprietary multi-coated lens to improve visibility and color transmission. The sight places electronics at the top of the housing to expand the usable viewing window while preserving a compact profile.

Applications: suited for everyday carry (EDC) pistol setups and competitive/precision pistol work or range training where rapid target pickup and durability matter. The design emphasizes environmental protection, battery life, and tactile controls without inflating size or weight.

Key user-facing features include the closed emitter to reduce acquisition lag, INSTANT-ON activation with auto shutoff to extend battery life, audible and tactile adjustment controls, and a machined 6061 aluminum housing with hard-coat anodization for durability. The RFX44 ships with hardware to fit RMR/SRO footprints and includes a Picatinny mount and a CR1632 battery.
