Thinking seriously about getting into the AR world and am drawn to the OR Sport II but am wondering about the one with the included CT red/green dot. Folks that own one, are you happy with it, or would I best served by a different optic. It’s going to be a defense rifle for generally non-rifle shooting people. I’d be thankful for any knowledgeable options since I’m ignorant of the AR platform and red dot sights both. Thanks!
