Holosun elite green dot optic - Holosun Elite 1x20 mm 2 MOA Dot Night Vision Compatible Solar/Battery Green Dot Sight

This is the second one of these that I've purchased. I really like the compactness of this optic. I also like that it comes with two different sized risers to adjust the height. The solar power panel is a handy option, and it greatly extends battery life. I also like the automatic brightness adjustment feature that adjusts the dot brightness in relation to ambient lighting. The only downside (and very minor) is the rubber lens covers; they slipped off very easily. I solved that problem with a set of Monstrum flip-up plastic lens covers.

Overall, I couldn't be happier with this optic
