Viridian RFX45 Closed Emitter 5 MOA Green Dot Reflex Sight ACRO/RMR

The Viridian RFX45 is a compact closed-emitter reflex sight purpose-built for defensive pistols. A native ACRO footprint is paired with an included RMR adapter plate, giving the RFX45 drop-in compatibility with the most common pistol optic cuts on the market today.

The sight uses a crisp 5 MOA green dot reticle projected through a fully multi-coated 24mm x 15.5mm window. Green is the easiest color for the human eye to pick up, which speeds up target acquisition in daylight, low light, and any condition in between. Because the emitter is fully enclosed, the LED is shielded from rain, dust, mud, and pocket lint - exactly what a hard-use carry optic needs.

The RFX45 is built around a machined 6061 aluminum housing finished in hardcoat anodized black, and it weighs just 1.73 oz while measuring only 1.90" long. Internally, it runs on a single CR2032 battery with up to 50,000+ hours of runtime, and offers 10 brightness settings - 8 visible plus 2 night-vision compatible levels. INSTANT-ON activation with onboard memory brings the optic to life the moment the pistol is drawn, while auto shut-off preserves battery life when the gun is holstered.

Tactile and audible 1 MOA windage and elevation adjusters make zeroing quick and positive, and the sight carries an IPX6 waterproof rating for reliable service in adverse weather. Backed by Viridian's reputation for innovation in electro-optics, the RFX45 delivers a rugged, feature-rich closed-emitter package for today's defensive pistol.
