The device has a high IP67 rating, making it resistant to weather conditions and temporary immersion in water. The aluminum body is finished with a hard anodizing technique, which provides high resistance to abrasion and scratches.

The Primary Arms by Holosun HS507C X2 pistol collimator uses an innovative sighting solution in the form of the ACSS Vulcan system.

How is the ACSS Vulcan reticle different from the classic red dot or dot with circle?

ACSS Vulcan revolutionizes the targeting system using a collimator. Instead of the standard red dot, a chevron (inverted V) mark is used, which allows quick target entry and precise shooting at longer distances. The aiming mark is supported by a large circle (with an option to turn it off), which helps to quickly position the chevron perfectly in the center of the target. If you lose the aiming point, you can see the outline of the circle on the edges of the lens, which helps you instinctively apply corrections and return to the desired target. The ACSS Vulcan reticle collimator provides a noticeable advantage over mechanical sighting devices when shooting fast at distant targets.

The Primary Arms by Holosun Micro Red Dot HS507C X2 uses lenses coated with multi-layer anti-reflective coatings that provide high light transmission and a clear and sharp image free of parallax error.

Solar powered

The collimator is powered by a CR1632 battery, which, according to the manufacturer, provides up to 20,000 hours of operation at a brightness setting of 6. In addition, the device uses a Solar Failsafe panel, which in strong light (sunlight or artificial) supports the operation of the battery, is responsible for automatic brightness adjustment of the aiming mark and replaces a discharged battery in an emergency situation. The user can use the automatic brightness adjustment or independently change the brightness have 10 daylight settings and 2 settings for night vision.

Battery saving system

With an impressive runtime of up to 20,000 hours, the device owes its battery life to the Shake Awake system, which automatically turns off the LED when there is no activity and the device goes into sleep mode. Re-activating the aiming mark requires only moving the weapon. The user can independently define the time after which the sleep mode is activated.
