Designed for rifles, shotguns, and other long gun applications, this HE510C Reflex Sight in a charcoal housing from Holosun features a red circle-dot reticle and a multicoated lens for clear and unobstructed targeting at close and long ranges. Built with an aluminum housing and a grade 5 titanium hood, the sight comes with a QD absolute co-witness mount with a 1.4″ dot height for added compatibility. The multiple reticle system has three options: a 2 MOA dot, a 65 MOA circle, and a combined reticle. The sight’s red Super LED is powered by a CR2032 battery, providing 12 brightness levels including two 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 after the battery fails.
