Viridian RFX45 Closed Emitter Green Dot 1x 24mm x 15.5mm 5 MOA ACRO/Picatinny Low Mount - Black Anodized

The Viridian RFX45 is a closed emitter reflex sight built around a 5 MOA green dot reticle and an ACRO-compatible footprint. Its fully enclosed housing protects the emitter and lens assembly from the elements, making it a rugged option for slide-mounted pistol use as well as long-gun backup duty.

At the core of the RFX45 is a machined 6061 aluminum housing with a black anodized finish and a fully multi-coated lens measuring 24mm x 15.5mm. The optic is powered by a single CR2032 battery and features INSTANT-ON activation with memory and auto shut-off for up to 50,000 hours of runtime. Audible and tactile windage and elevation adjustments click at 1 MOA per step, and the unit carries a waterproof rating for reliable field use.

The 1x optical system offers unlimited eye relief and presents a daylight-bright 5 MOA green dot that is fast to pick up under stress. At just 1.90" long, 1.1" wide, and 1.13" tall, the RFX45 weighs only 1.73 oz, keeping the optic compact and lightweight on a slide, PCC, or backup rifle.

This 9810059 variant ships with a low-profile Picatinny mount included, allowing direct attachment to any standard Picatinny rail in addition to ACRO-pattern cuts. Whether you run it on a pistol slide, a PCC, or as a long-gun secondary optic, the RFX45 delivers a compact, enclosed green-dot package backed by Viridian's reputation for weapon-mounted electronics.
