The Primary Arms by Holosun HE507K-GR-X2 Green ACSS Vulcan Dot features multi-coated anti-reflective lenses for high light transmission and a clear, sharp parallax-free image. The control module and LED are resistant to shock, recoil, and weather, ensuring reliable performance even in harsh field conditions.

How does the ACSS Vulcan Dot reticle differ from a classic dot or dot with circle?

ACSS Vulcan Dot revolutionizes red dot aiming. The green dot reticle is supported by a broken partial circle (optional), which helps quickly center the reticle on the target. If the aiming point is lost, the circle edge helps instinctively adjust and reacquire the target. The ACSS Vulcan Dot sight provides a noticeable advantage over mechanical sights during rapid long-range shooting.

The sight is powered by a CR1632 battery, providing up to 50,000 hours of operation at brightness level 6. Users can use automatic brightness adjustment or manually select from 10 daytime and 2 night settings. The impressive runtime of up to 50,000 hours is achieved by the Shake Awake system, which automatically turns off the LED when idle and puts the device into sleep mode.
