The open frame of the HS510C Open Reflex Circle Dot Sight allows users a broad sight image. It is always on and is powered by a solar cell when in regular use, with a backup battery providing additional power in low light. By pressing a button, the reticle can be changed from a 65 MOA circle with a 2 MOA dot to a 2 MOA dot only. Even better, since the same LED projects both reticles, there is no need to re-zero.
