I was not new to ARs when I bought my M&P Sport as I've owned ARs in the past and been in the military. I bought my M&P Sport because I knew S&W makes quality weapons so it would be a good base to build into whatever form of an AR I decided I wanted. It has been a good rifle through about 1000 rounds so far and only malfunction was due to a magazine not fully seated. Can't blame the rifle for operator error.
