Viridian RFX45 Closed Emitter Green Dot Sight 1x 24mm x 15.5mm 5 MOA - ACRO/Glock MOS

The Viridian RFX45 is a closed-emitter reflex sight built for fast, daylight-bright aiming on optics-ready pistols. Its 1x magnification pairs with a wide 24mm x 15.5mm objective window and a crisp 5 MOA green dot reticle that draws the eye quickly and stays visible in bright sun without overwhelming the target picture. The fully sealed emitter keeps the optic running through rain, mud, and debris, making it a strong choice for concealed-carry and duty slide-top use.

Machined from 6061 aluminum with a durable black anodized finish, the RFX45 weighs just 1.73 oz and measures only 1.90 in long, keeping the slide profile trim. The sight runs on a single CR2032 battery rated for up to 50,000 hours and features INSTANT-ON activation with memory and auto shut-off so it wakes up the moment you draw. Audible and tactile windage and elevation adjustments let you zero with positive clicks, and fully multi-coated lenses deliver a clear sight picture with unlimited eye relief.

The RFX45 footprint follows the ACRO mounting pattern and ships with a Glock MOS adapter plate, giving you a direct, low-profile mount on optics-ready Glock MOS slides as well as any pistol or platform cut for ACRO. Waterproof construction and a rugged closed-emitter housing round out a package aimed at shooters who want a dependable green-dot option for EDC, home defense, and range use.
