Holosun Technologies has always set an example for others to follow in the weapon industry, and this time is no different. The open reflex circle dot sight features an open frame for wide sight picture to allow you to view your target and take precise aim.

To ensure your optic lasts you a lifetime, the optic features a solar panel, running on solar power. When that runs out, the CR2032 battery kicks in, giving you 50,000 hours. You can also switch between three MOAs, a 65 MOA circle with 2 MOA red dot, a 2 MOA red dot only, and a 65 MOA ring only.

All you need to do is click the button and it will switch to your preferred MOA red dot. You also receive a QD mount and use it with a variety of weapons such as pistols, air rifles, crossbows, and shotguns. Some other features include an unlimited field of view, shock-resistant, waterproof, and 1x magnification. It's titanium-alloyed and 6061 aluminum body ensures durability and longevity.

If your profession or hobby takes you outdoor, you need to use this optic due to its ability to operate during extreme weather conditions and allowing you to choose from 10 daylight and 2-night vision settings to help you shoot outdoors.

The HS510C Open Reflex Circle Dot Sight has an open frame for a wide sight picture. It is powered by solar cell under normal usage, and a back-up battery to supplement power requirements in low light conditions. The reticle can be switched between a 65 MOA circle with 2 MOA dot, a 2 MOA dot only, or a 65 MOA ring only at the push of a button. Better yet, the same LED projects both reticles, so no re-zeroing is necessary.
