Special Features
- The titanium-alloy protective hood wraps the front of the optic and shields the emitter and lens from direct impact, muzzle blast, debris, and rail flex that would compromise an unprotected open emitter housing under hard field and duty use.
- The Multi-Reticle System gives you three distinct aiming configurations: 2 MOA dot only for precision shots, 65 MOA ring only for maximum close-range speed, or the full circle-dot combination for a versatile aiming solution that covers close-quarters through mid-range engagements in a single optic.
- The 65 MOA ring equates to approximately 68 inches at 100 yards, giving you a built-in range estimation reference and a fast-acquisition speed ring for shotgun patterns, moving targets, and close-quarters stage work where a small dot alone slows acquisition.
- Solar Failsafe uses the integrated solar cell as both a secondary power source and an ambient light reference, keeping the reticle fully functional in any lit environment even after the CR2032 battery reaches complete depletion.
- Shake Awake powers the sight on the instant the rifle moves and shuts off after a selectable inactivity period, preserving the full 50,000-hour battery reserve between range sessions and storage without any manual power management.
- The multilayer multi-coated lens maximizes light transmission and reduces glare across the full window surface, giving you a clean, high-contrast green reticle picture in bright sunlight, overcast conditions, and transitional lighting environments.
Practical Benefits
- The large 0.91 x 1.26 inch window gives your eye a wide, unobstructed sight picture that makes the reticle fast to find on a rapid mount and lets you track moving targets and stage transitions without the window edge clipping your view.
- The included quick-release mount installs tool-free onto any standard Picatinny or Weaver rail, so the HE510C-GR goes directly from the box onto your carbine, PCC, or shotgun without sourcing additional mounting hardware.
- The 2 night vision compatible brightness positions make the HE510C-GR a functional option for hunters, patrol rifle users, and competition shooters who run low-light stages or pair their long gun with night vision devices.
- The titanium hood makes the HE510C-GR a practical choice for patrol rifles, hard-use hunting builds, and competition guns that see consistent handling, transport, and contact with gear and cases between uses.
- Your HE510C-GR gives you a solar-backed, shake-activated, titanium-protected green dot on your long gun with a large window and 50,000-hour battery life, so your carbine, PCC, or shotgun is always ready without checking power levels or manually activating the optic before a stage or a hunt.
The Holosun HE510C Elite Green Dot Sight (HE510C-GR) with its 65 MOA ring and 2 MOA green dot is a smart addition for carbine shooters, patrol rifle users, and competition builders who demand a large-window, solar-backed, titanium-protected open reflex sight with multi-reticle versatility and a quick-release mount ready to run out of the box.
