The Viridian RFX1 is a reflex sight designed specifically for the Smith & Wesson Bodyguard 2.0, delivering a true custom fit that follows the slide s serrations and overall geometry for a streamlined, integrated look. This purpose-built optic installs directly with no modifications or plates required, maintaining the pistol s slim profile for ideal concealed carry. As the smallest green dot sight on the market, the RFX1 delivers high performance without adding bulk. A crisp 3 MOA green dot and fully multi-coated glass provide fast, accurate aiming in any lighting condition. An auto-brightness sensor instantly adapts to surrounding light, while Viridian s INSTANT-ON technology activates the optic the moment the firearm moves no buttons or delay. Constructed with a machined aluminum housing, the RFX1 is shockproof, IPX4 water-resistant, and weighs just 0.53 oz. Designed for everyday carry, it offers durability and precision in a compact, lightweight package.
