Holosun HE507C-GR X2 ACSS Vulcan Micro Reflex Green-Dot Sight – 1×, RMR Footprint, Solar/Shake-Awake
The HE507C-GR X2 ACSS Vulcan blends Holosun’s proven 1× micro-reflex platform with Primary Arms’ intuitive ACSS reticle, giving shooters a 10 MOA chevron centered inside a 250 MOA outer circle for rapid target acquisition and precise holds. A rugged 7075-T6 aluminum housing, dual solar/CR1632 power, and an RMR-pattern footprint make this optic a ready upgrade for duty pistols, PCCs, or offset rifle mounts.
Condition

What’s Included
- Holosun HE507C-GR X2 ACSS Vulcan micro-reflex green-dot sight with solar fail-safe, Shake-Awake, Lockout mode, IP67 rating, and side-loading CR1632 battery tray
- Integrated RMR-pattern four-screw mounting plate (screws not included)
This open-emitter optic uses Holosun’s dual-power system: a top-mounted solar cell provides runtime in bright light, while the side-loading CR1632 battery powers the sight in low light and delivers up to 50,000 hours of life on medium settings. If the sight sits still, Shake-Awake powers it down to save battery; the first movement instantly reactivates the reticle.
The ACSS Vulcan reticle’s outer 250 MOA circle disappears when you present the pistol correctly, acting as a real-time training aid that guides your eye back to center if the gun is canted off-axis. The 10 MOA chevron offers a fine aiming point without obscuring small targets, and 12 brightness levels—including two night-vision settings—accommodate bright daylight, indoor ranges, and NODs-equipped shooting.
Precision 1 MOA click adjustments simplify zeroing, while parallax-free glass and unlimited eye relief maintain a consistent point of impact from any shooting position. The sight meets IP67 standards for water and dust resistance, so rain, mud, and recoil won’t compromise performance.
