Holosun HS503CU Solar Micro Sight (Red Circle-Dot Reticle)

Made for rifles, carbines, and other long-gun applications, this HS503CU Solar Micro Sight from Holosun features a red, circle-dot reticle and a multicoated lens for clear and unobstructed targeting at close and long ranges. Built with a 6061 T6 aluminum housing, the sight comes with two mounts, including a 1.63" lower 1/3 co-witness mount and a .75" low mount for low-comb height rifle applications. The multiple reticle system has three options: a 2 MOA dot, a 65 MOA circle, and a combined reticle. The sight's circle-dot Super LED has ten daylight brightness levels and two night-vision settings. It is powered by a CR2032 battery for 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 after the battery fails.
