Designed for rifles, shotguns, and other long gun applications, the Holosun RONIN Multi-Reticle Reflex Sight features a green circle-dot reticle and a multicoated, extra-large lens for clear and unobstructed targeting with an increased field of view. Built with a 7075 T6 aluminum housing, the sight comes with an absolute co-witness Picatinny mount that puts the dot 1.42" above the rail.The multiple reticle system has three options: a 2 MOA dot, a 65 MOA circle, and a combined reticle. The sight's green Super LED is powered by a CR2032 battery, providing 12 brightness levels including four night-vision settings, and delivering 50,000 hours of battery life. The battery is backed up by Holosun's Solar Failsafe technology, which uses solar power to keep the sight working if the battery fails.
