Viridian 9810052 RFX45 Pro Black | 24 x 15.5mm 5 MOA Green Dot Reticle

The Viridian RFX45 Pro green dot sight brings the visibility advantage of green LED technology to your pistol or carbine optic setup. Built on Viridian's two decades of innovation in weapon-mounted optics, this closed-emitter reflex sight pairs a bright 5 MOA green dot with a compact 24x15.5mm footprint—ideal for shooters who demand a crisp sight picture without the bulk of magnified glass. Whether you're running it on a carry gun, a home-defense rifle, or a competition pistol, the RFX45 delivers the speed and accuracy of a quality non-magnified dot in a package designed for real-world use.

The sight is housed in precision-machined 6061 aluminum with fully multi-coated optics for durability and light transmission. It ships with both Micro Red Dot System (MOS) and RMR adapter plates, plus high and low Picatinny mount options—so whether your gun is already drilled and tapped or sits on a rail, you've got the hardware to get running. The green dot itself is a game-changer if you've shot with standard red emitters: it's simply easier to see in bright sunlight or at distance, making target acquisition faster and more reliable.

Tactile and audible brightness adjustments let you dial the reticle in by feel or ear, and the INSTANT-ON activation with memory means the dot comes back at your last setting every single time you draw. Battery life stretches to 50,000 hours on a single cell, and auto-shutoff protects against a dead battery in your range bag or nightstand. This is a sight built to work, not impress—the kind of optic that earns trust through dependable performance.
