Holosun HS510C Green Dot Open Reflex Sight – Flat Dark Earth

The HS510C is Holosun’s full-size open reflex sight for long guns. The large, open lens gives you a wide field of view, so you can keep both eyes open and pick up the dot fast on a carbine, pistol-caliber carbine or shotgun. The flat dark earth finish matches tan and FDE builds.

Three reticles, one zero

Holosun’s Multi-Reticle System lets you choose a 2 MOA dot for precise shots, a 65 MOA circle for fast close-range work, or both together. All three come from the same LED, so switching reticles doesn’t change your zero. The 540nm green emitter is easy to see in bright daylight.

Power you can count on

• Solar Failsafe: a solar cell backs up the battery and runs auto-brightness that adjusts to the light around you.
• Shake Awake: the sight powers down when it sits still and comes back on the instant it moves.
• Long battery life: up to 50,000 hours on one CR2032 (setting 6), with a side-loading tray, so you don’t have to pull the sight to swap the battery.
• 12 brightness settings: 10 for daylight and 2 that work with night vision.

Built for hard use

The aluminum housing has a titanium hood to protect the lens from impacts, and it’s sealed to IP67 against water and dust. The built-in quick-detach Picatinny mount puts the dot at 1.41″, an absolute co-witness with standard AR iron sights. A lower 1/3 co-witness spacer (1.63″) is sold separately.
