I've owned several AR's, among them Armalite (2), S&W (2), Les Baer (1), and a couple more that I never got around to firing. I now own a daniel Defense and an FN. The Daniel Defense is my favorite among the ones you can purchase. It is built as good as it can be. With all the right parts and all the right procedures. Very accurate and very reliable. I like the FN as well, or perhaps a little better, but FN is not available as a purchased product. Both are "better" (pretty subjective outside of combat) than the other AR's I've owned. All were good though, all have been accurate, all have been reliable. The AR is a great design that's reliable, and excellent for accuracy. Suppose that's why it's held up so long as a military arm.
