I don't think the author had ever fired a gun before, or was lying if he had, if he felt the AR15 has "horrifying". After getting my first single shot 12 guage at 13, I didn't buy a magazine fed semi auto until 16. I had 3 years of shooting a very light, shooting average load 12 guage rounds by the time I first shot an Ar15 A2 heavy barrel. The first thing I thought was "wtf is this sproiiing" sound (the buffer tube/spring working in the fixed stock always makes this sound/feeling), and the second was "wow, this doesn't recoil very much at all". Any adult trying to make the Ar15 or any 556 auto loading rifle seem "horrifying" is either very, very inexperienced, as in 1st timer pretty much, OR, has an obvious agenda to make such rifles seem "scary".
