There is also an AR 7. It is a rifle that shoots .22LR rounds. It was primarily designed for paratroopers, or so I'm told, as the barrel assembly can be removed and slid into the buttstock assembly, making the rifle easy to fit into the buttstock, which in turn fits into a small backpack. Handy, but my father in law said they were picky eaters as far as ammo went. Some brands would not cycle properly. I know very little else about it, other than what I am told by word of mouth. Anyone who has more knowledge on it is welcome to chime in.
