Viridian RFX11 Features The Viridian RFX11 projects a crisp 3 MOA dot through multi coated glass optics across a 16mm by 22mm lens giving a fast precise aiming point for close and mid-range engagement. INSTANT-ON operation paired with an ambient light sensor and automatic brightness control means the dot adjusts to the surrounding light without the shooter touching a button. Unlimited eye relief and 90 MOA of total windage and elevation adjustment give a wide forgiving sight picture along with plenty of room to zero the optic precisely. A single CR2032 battery delivers roughly 30 000 hours of run time on the middle setting keeping the sight ready for the long haul. Built from high strength thermomolded polymer the RFX11 weighs just 0.44 ounces and measures 1.6 by 1.0 by 0.9 inches making it one of the lightest reflex sights available for a carry pistol. It uses the Shield RMSc mounting footprint and is designed to work with an optic plate on the Walther PDP and WMP directing shooters toward a direct secure mounting solution on those platforms. IPX4 waterproofing and an operating range of negative 4 to 130 degrees Fahrenheit let the sight hold up to sweat rain and demanding environments alike. Backed by a limited lifetime warranty the RFX11 is built to be a dependable everyday optic for concealed carry or close-range offset use on a rifle.
