Hello Forum, Hopefully this is not a topic that is already well covered. I have seen several companies that make scopes designed for the 5.56 mm NATO AR rifles, but I am guessing that they might not be good for a 7.62 NATO AR as the ballistics of the two are different. For example, one .223 AR scope already has incremental markings in the view, going out to 600 yards. I am guessing that it is not as likely to find a scope designed specifically for the .308. Does anyone know if there a scope designed for an AR .308? In a variable power scope, I figure that 1X or 2X on the low end, and 8X to 12X on the high end would be good. Thanks for your suggestions and help.
