Extremely good alternative to high end optics - Holosun HE510C Elite 1x 2MOA Reflex Green Dot Sight

I highly recommend this optic. No issues with seeing the reticle in daylight. Battery is convenient as well. I've heard that the mounts weren't that great, however, I haven't lost zero yet through a few hundred rounds. I also have astigmatism, but can see the circle and dot clearly. I use this for an AR 9mm and it works well for it! It's pretty rugged and solidly built. Good alternative to EOTech.
