I want to thank everyone for the great replies. I appreciate you spending the time to answer my question.

To the point, I did buy an AR but I decided after considering what I wanted to change or add I should probably consider looking at other ARs as well. I know this may be somewhat controversial to some but I decided to purchase a Springfield Saint. I know it doesn't have the proven track record of the Sport II as it is a new offering, however, it came setup with some of the things I would have changed on the Sport and I liked the mid level gas system and the trigger is amazing. I also really like the BCM Tupperware which I like and won't change. There are some other things I liked about the Saint but they are probably nitpicking by comparing. Time will tell if I made the right decision but from my initial impressions and from my two outings shooting it I am pleased which is I guess what counts.

Thanks again!
