Viridian RFX44 Compact 5 MOA Green Dot Reflex Sight

The Viridian RFX44 is a compact reflex sight engineered for rapid target acquisition on pistols. It uses a 5 MOA green dot reticle and a closed-emitter design to improve dot acquisition and protect the optical elements from environmental contaminants. The sight is built with a machined 6061 aluminum housing and places electronics on the top of the unit to maintain a low profile while maximizing the viewing window.

Designed for everyday carry, duty, and competitive pistol use, the RFX44 pairs with Glock MOS plates or mounts using the Aimpoint ACRO footprint for straightforward compatibility with MOS-cut slides and adapter plates.
