I personally never cared much about what jim zumbo wrote. But, the theory is that whatever first comes to mind and, if that is what you say, you probably believe it.
The poor scribe says he was tired? Your basic beliefs vary according to your moods?
I personally do not own an M16/AR15 but without fully automatic setting they are nothing but an individuals semi-auto weapon (yes a weapon like the ones that with brave soldiers bought and preserve our freedom)not in the same class as an atomic sub though, as some antis might try to draw an analogy.
I would miss my walnut and blueing, but would have to argue that most military type rifles make decent hunting rifles!
