ZeroTech Optics now offers its Thrive HD 1x Micro Prism in Flat Dark Earth. The sight uses an etched circle-and-dot reticle with a 3 MOA center point, 13 red illumination settings, shake-awake electronics, and a 50,000-hour battery in a side tray.

It weighs 7.55 ounces and includes four mounting heights plus Aimpoint T2 footprint compatibility. Magnification exceeds true 1x at about 1.1 to 1.2 power, producing a double image closer than 20 yards when both eyes remain open, yet the 20 mm lens stays clear and allows backup iron sights plus a rear magnifier.
