This open reflex sight with red reticle offers a multi reticle system with switchable reticles, an efficient solar panel with automatic brightness control, a wide front lens, and a durable alumin housing with titanium hood. It's ideal for dynamic disciplines.

The Holosun HS510C can be mounted on the Steambow M10 at the perfect sighting line and height. Remove the front unit and mount the Holosun 510C on the now exposed Picatinny rail. For longer distances, it may be necessary to give this rail a forward tilt. For this reason, the lower Picatinny rail is removable. To do this, place an M4 washer under the rail at the rear screw so that the rail is tilted forwards. For extreme distances, 2 washers may even be necessary.

All Holosun reflex sights are high-quality optics built to military standards at an unbeatable price - without compromises. They allow for quick targeting with both eyes open. In addition to the interchangeable reticles of the 500 series and the solar models of the C-line, they all also feature an intelligent Shake Awake™ function for an exceptionally long battery life, absolute parallax freedom, a tilted front lens (micros and tubes), and 12 brightness levels (2 night, 10 day) for manual brightness adjustment in different lighting conditions. Our sights can be used in combination with laser target sights, night vision devices, and night vision goggles.

The optic has a built-in supercap. This additional power source allows the red dot sight to operate without a solar cell/light or battery, providing an additional backup of approximately 200 hours of continuous use in dot mode (level 6).
