True, the M14 was the last non-ugly military rifle.
I thought the FN-FAL was pretty good-looking, too. In fact, the M-14, to me at least, looks its best when it uses -5 or -10 shot magazines, vice the standard-sized ones, which is highly unusual for a semiauto.
It looks cleaner and more streamlined that way.
actually the M-14 is ugly. I think the Garand is the last good looking military rifle.
