Holosun 510 green - Holosun HE510C Elite 1x 2MOA Reflex Green Dot Sight

Very nice, absolute co witness with Yankee Hill back up sights, and the green seems better for picking up quickly, although red seems better for outside surroundings, as there's much in nature that's Green, and it plays tricks with my lousy eyes. I own both Red and Green versions of the 510c, and can say with confidence, it's a fantastic unit. I also own EOTech, and find the Holosun has a crisper image, and at a better price
