Damn, Jsick, you got the rifle I want. How much did it cost, if I may ask?
I fired two different Ruger 556's at an expo last year a few times. One had a red dot sight, the other was scoped like in that video you posted there. I wasn't a fan of it in the red dot (Though I loved that style scope on the .22 version, strangely enough), but man was it still awesome. Shines when shooting downrange. I loved it, I really should buy one.
