Awesome green dot, build and features - Holosun Elite 1x20 mm 2 MOA Dot Night Vision Compatible Solar/Battery Green Dot Sight

The only thing I don't like is that this is made in China but otherwise you can't beat it. Nearly unlimited battery life with the solar power. I prefer green dots over red because the human eye reacts to Green faster than any other color on the spectrum. I haven't used this extensively but it hasn't lost zero yet. Dual mounting options and this is one optic where the LED emitter does not obstruct your view and for me that's huge. If only this was made in America but you really can't beat these for the price.
