Inside the Holosun HS510C Reflex Optic
The HS510C open reflex circle dot sight features dual power supplies with solar power during daylight usage and battery backup during low light conditions.
Due to its open-frame design, the HS510C offers a wide field of view for better situational awareness. It is also parallax-free and has unlimited eye relief.
The reticle can be switched between a 65 MOA circle with 2 MOA dot, a 2 MOA dot only and a 65 MOA ring only using a single button.
There are 10 daylight and two night vision illumination settings that can be selected by using the +/- buttons. This model uses a red reticle but a version with a green reticle is also available.
A quick detach mount is standard.
