    IMO accuracy with a 20 is not better than a 16 just because of barrel length unless you plan to use iron sights.
    Sounds like run of the mill stuff without knowing what brand, 4140 steel is the softest and can wear out quicker than 4150 but, it is harder than stainless.
    "Glacierguards" sounds like DPMS to me, I'd look around a bit more JMO.

    I have a theory that shorter barrels are more accurate because they are stiffer...


    And in my opinion, the real beauty of the AR is the ability to change out any part if its not to your liking, including barrels.

    Daniel Defense makes the good stuff. It depends on how much you want to spend.

    Accuracy wise, it is the quality of the barrel. The advantage to the 20 inch barrel is a bit more velocity, if you need it. For serious purposes, you can use expanding bullets so velocity is not that important.

    If I was just starting out, I would get the S&W. Once you learn a bit you will know what you want.
