Thanks for the heads-up. I have one coming my way. I might give it to my son as a Christmas gift. He's a college student, and he decided to buy an AR this summer just in case the upcoming elections go the wrong way. Being on a limited budget, he decided to buy a Ruger 556, and it came bare with no sights. Since then, he purchased a set of irons, but I figure this scope might make a nice gift.
