Holosun HS507C X2 open reflex sight - ACSS with Vulcan reticle

The HS507C X2 with the ACSS Vulcan reticle is an open reflex sight designed for use on pistols. The sight is designed for heavy use and is great for sports shooting and professional use.

The HS507C X2 ACSS takes the performance of its predecessors to the next level with a new lock function, first introduced in the 2018 LEM series. When enabled, the lock function prevents accidental button presses and settings from being changed.

The HS507C X2 ACSS lens is protected with a multi-layer coating to prevent scratches and reflections. The parallax-free design, unlimited eye relief and ACSS Vulcan reticle pattern ensure fast and accurate target acquisition in all weather and light conditions. Its features include Solar Failsafe and Shake Awake function. The scope is equipped with an impact-resistant 7075 T6 aluminum body and is water and dust resistant.

ACSS Vulcan reticle

The revolutionary patented ACSS Vulcan reticle pattern provides a large circle that guides the eye to the 10 MOA center dot, eliminating one of the biggest challenges users face with red dot sights. If the reticle is not centered, a portion of the large circle appears at the edge of the field of view, providing an immediate clue as to how to center the reticle. When the reticle is exactly centered, the large circle disappears from view entirely, indicating that the center dot is properly aligned. This patented reticle feature significantly improves the functionality and speed of the sight. It eliminates the common frustration associated with searching for the center dot.

Shake Awake™

Shake Awake technology is a standard feature on all current Holosun optics and helps extend battery life by turning off the optic’s LED when not in use. A sensitive motion sensor detects movement, keeping the LED on during use. This allows for effortless use during the day or shift. When the weapon is stored at the end of the day or shift, the motion sensor detects inactivity and after 10 minutes (default setting), Shake Awake technology turns off the LED until movement is detected again. Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be disabled completely if desired. Touching the optic instantly activates the LED, so the Holosun optic is ready to use when needed.

Solar Failsafe™

Solar-powered Failsafe technology provides peace of mind in the event of a low battery, allowing the scope to be used in natural or artificial light. In Auto mode, the reticle brightness automatically adjusts to match the amount of ambient light. Solar Failsafe™ allows the scope to be operated on solar power, providing additional peace of mind in the event of a low battery. The scope can operate indefinitely in daylight and darkness thanks to a supercapacitor that maintains a charge via the Solar Failsafe system without a battery.
