Holosun HS510C Open Reflex Green Multi Reticle Solar Collimator - FDE

Open-reflex collimator sight. The open design with a large sight window (23 x 32 mm) provides a very wide field of view and comfortable binocular aiming, which significantly facilitates quick target acquisition. The model allows you to choose one of three green reticles: a 2 MOA dot, a dot with a circle and four positioning points, or a 65 MOA circle alone. The housing is made of durable and damage-resistant aluminum. Seals ensure resistance to water and dust. Powered by a solar cell, which is supported by a battery in low-light conditions.

The design provides a wide field of view. The housing is made of aluminum, and critical components are protected by an additional titanium coating. The material used is highly resistant to mechanical damage. The collimator meets the IP67 sealing standard, guaranteeing complete protection against dust ingress as well as submersion in water for up to 30 minutes at a depth of up to 1 meter. Its robust design ensures shock resistance up to 1000 G.

The collimator is equipped with the Multi Reticle System (MRS), which allows you to select one of three red reticles: a 2 MOA dot, a 65 MOA circle, or a dot-and-circle combination. All reticles are displayed using a single energy-efficient LED. The optical system is parallax-free and offers an unlimited eye relief. The lenses are coated with multi-layer coatings that ensure high light transmission and a clear, high-contrast image.

The reticle has 10 brightness levels for daytime use and 2 levels optimized for use with night vision devices, allowing the sight to be adapted to various lighting conditions. Vertical and horizontal adjustment is possible within a range of +/- 50 MOA.

The model uses Solar FailSafe technology, in which a built-in solar cell can directly power the device in good lighting conditions. In lower light, the system is supported by a CR2032 battery, which significantly extends its operating time. Additionally, the solar panel acts as a light sensor, automatically adjusting the brightness of the reticle to match the ambient conditions. The model is equipped with the Shake Awake energy-saving system, which automatically puts the device into sleep mode after a period of inactivity and then immediately wakes it up upon detecting motion. The collimator remembers the last-used reticle and brightness level.

The collimator is powered by a CR2032 battery, providing up to 50,000 hours of operation when the dot is set to medium brightness, and up to 20,000 hours when the dot is set to the circle reticle.

The collimator is equipped with a steel quick-detach (QD) mount, which allows for quick attachment of the device to a Picatinny or Weaver rail.
