    I just got my upper today and was able to put a few rounds though it 300 . I know that’s a very low number in the big picture but I have to say….. Very nice!! Wow what away to make you feel right away that you are shooting something that’s above most other components in this price range. It was prefect .. Predictable so easy with 223. And 556 there’s no difference in the feel. If you do your part this set up will do his.. ( by the way running a Nordic lower also) I work at a range so this is just the beginning of what I run in this riffle. Can’t wait to get out to the outdoor range.

    OK an update from my last review last week..got out to the range this weekend.. 200 yards..result? This upper make’s me look great! Again it’s very accurate.. With good ammo…polymer tip. Tap and regular 223 .. It just gets the job done period! I will upgrade my scope and see where I can take it too. Looking forward to it. Like I mentioned I work at at indoor range its so good after another 200 rounds I came to the conclusion that it way to much rifle ..waste of ammo its that good.
