Holosun HE510C-GR Green Dot Sight

The battery life on this is insane; I’ve had it on for weeks and it’s still going strong, and the green dot stays perfectly visible in bright sunlight with the solar failsafe.

Green dot is noticeably crisp even in bright daylight, and the multi-reticle system lets me switch between a 2 MOA dot and a 65 MOA circle instantly depending on what I'm shooting that day. The solar panel on top actually keeps the reticle visible without needing to touch the battery, which surprise

The solar failsafe kicked in during a cloudy day and my dot never flickered, so I’m confident this will run forever. The green reticle is crisp even in bright sun, and switching between the dot and circle-dot is instant.
