The Holosun HE512T-RD is an enclosed reflex optical sight designed for rifle and carbine applications. Built with Grade 5 Titanium housing, it includes an absolute co-witness mount at 1.41″ dot height. Made for carbines, shotguns, and other long-gun applications, this reflex sight features a multicoated, parallax-free lens for clear targeting at close and long ranges. Versatile for long gun platforms, the HE512T-RD is at home on carbines, PCCs, and shotguns due to its durable design.
The Multi-Reticle System offers three options: a 2 MOA dot, a 65 MOA circle, and a combined Circle Dot reticle. Features include Holosun’s Super LED with up to 50k hours battery life, Solar Failsafe, and Shake Awake. The Red Super LED is powered by a CR2032 battery, providing ten daylight brightness levels and two night-vision compatible settings. The battery is backed up by Solar Failsafe technology, which uses solar power to keep the sight working after battery failure.
Grade 5 Titanium results in unparalleled strength and durability—Holosun Grade 5 Titanium has more than double the tensile strength and five-times the fatigue strength of 7075 Aluminum. Grade 5 Titanium is able to withstand seawater corrosion, making Holosun Titanium model optics suitable for use in maritime environments. The sight is IPX8-rated waterproof.
