Vortex Optics Razor Red Dot Sights The Razor Red Dot Sight-6 MOA is designed to be mounted to a wide variety of firearms and used in various shooting applications. The Razor was designed so shooters have unlimited eye relief for easy target acquisition. A premium wide field lens gives the shooter an impressive field of view. The daylight bright red dot has nine illumination levels allowing shooters to find their ideal brightness setting and easily adjust if conditions change. Anti-reflective XR coatings on the lenses increase light transmission for maximum brightness while Armortek coatings protect the lenses from oil and scratches. O-ring sealed and a rugged one piece chasis constructed from aircraft grade aluminum ensure waterproof and shockproof performance. The Razor runs off a single CR2032 battery which can be easily switched in and out.
