Holosun Primary Arms HS507C-X2 Solar Powered ACSS Vulcan Collimator - Black

The HS507C X2 collimator sight, developed in partnership with Primary Arms. Open-frame design with a large viewing window (23 x 16 mm) provides a very wide field of view and comfortable binocular aiming, which significantly facilitates quick target acquisition. This model features the ACSS Vulcan aiming point. The housing is made from durable, damage-resistant 7075 T6 aluminum, and the installed seals protect against water and dust. It is powered by a solar cell, which is supplemented by a battery in lower light conditions. In the X2 variant, a horizontal button layout is used for even more intuitive operation.

The device body is made of robust 7075 T6 aluminum with a black anodized finish. The construction is vibration-resistant up to 5000 G and meets the IP67 standard, ensuring protection against dust and water immersion for up to 30 minutes at a depth of up to 1 meter. The working temperature range of -30 to +60 degrees Celsius allows the sight to be used in a wide variety of environmental conditions.

The model is equipped with the ACSS Vulcan aiming point. The optic offers 10 brightness settings as well as 2 additional levels dedicated for use with night vision devices. When switched off, the device remembers the last used reticle and its brightness level. The sight is fitted with adjustable controls that can be locked. This solution prevents accidental changes to the settings.

Automatic brightness control system adjusts the illumination intensity to the environment, while the manual mode enables precise adjustment to the user's preferences. The position of the reticle can be adjusted with an accuracy of 1 MOA per click over a range of +/- 50 MOA, ensuring precise point-of-impact setting.

The collimator uses a 23 x 16 mm viewing window that delivers a clear image and makes target acquisition quick and easy. Multi-layer anti-reflective coatings improve light transmission, and minimized parallax allows instinctive aiming regardless of the viewing angle.

The collimator is powered by a CR1632 battery, providing up to 50,000 hours of operation, thanks to a highly efficient diode and control electronics. A low battery level is indicated by a flashing reticle. The second power source is a Solar Failsafe system, featuring a solar cell on top of the housing. Depending on light intensity, the cell can power the LED entirely or work in conjunction with the battery.

The Shake Awake system uses a motion sensor to automatically wake the device from sleep mode when weapon movement is detected. If no activity is registered, the sight enters sleep mode after 10 minutes, significantly reducing power consumption and extending battery life.

The sight comes with a mounting system utilising interchangeable adapters in the RMR standard.
