The Holosun HE510C-GR Elite is an open reflex sight built to work hard on modern rifles, carbines, PCCs, and shotguns. This 1x magnification optic combines a rock-solid aluminum housing with a titanium hood to absorb impact and keep running through hard use. The green reticle puts your target in focus fast, and the included quick-release mount installs with absolute co-witness positioning for intuitive target acquisition on any platform.
What sets the HE510C-GR apart is Holosun's proven reliability tech. Dual power (solar + battery) means you're never caught dark—the sight charges in daylight and backs up with up to 50,000 hours of battery life on a single cell. Shake Awake auto-brightness kicks on when you move, saving power when the gun sits. Twelve intensity settings split between daylight and night vision compatibility, so you stay effective from dawn until long after sundown. The multi-reticle system gives you flexibility: circle dot, 2 MOA dot, or 65 MOA circle—pick what works for your shooting style.
Parallax-free and unlimited eye relief mean you get a full sight picture from any shooting position or distance. The convenient tray battery compartment makes swaps fast, and the Flat Dark Earth finish blends seamlessly into most modern builds while resisting glint and weather. Built for shooters who demand a reflex sight that keeps up with their pace.
