Vortex Razor AMG UH-1 Red Dot Sight. Available Late Summer 2017 The incredible features of the Vortex Razor AMG UH-1 Red Dot are matched only by its tough, tenacious performance. Absolute zero distortion and an impressive sight picture with unobstructed view ensure rapid, instinctual target acquisition. The shatterproof XR plus fully multi-coated windows and holographic elements are incredibly durable and promote optimal light transmission. All sensitive components are protected in the base of the sight, increasing durability, while eliminating the need for an obstructive secondary shroud. Fully Multi-Coated Anti-reflective lens coatings on every lens surface allow for brighter views. Brightness Settings 15 Levels Unlimited Eye Relief Non-critical eye relief for rapid target acquisition. Parallax Free All red dot and holographic sights will exhibit some small amount of parallax. Matching current industry practice, this small amount would be considered 'parallax free' and will make a negligible difference in the UH-1’s performance. Shockproof Rugged construction withstands recoil and impact. ArmorTek Ultra-hard, scratch-resistant coating protects exterior lenses from scratches, oil and dirt.
