Good choice. Upper and lower fit on my set was tight. I know some say that slop doesn't effect accuracy but I hate it. One issue that I did run into was the trigger to safety fit. It may have been the combo of the parts or the lower itself. But the safety was sitting to low and would not allow the rear of the trigger to come up far enough during the cocking process. I love mine.
