Why no one ever made an AR7 type gun in a bolt action is beyond me.
It's a neat rifle. The whole idea of a takedown that packs into a floating stock has a lot going for it. The only problem with the guns (and the reason I got rid of mine) is that they are unreliable. Some guys have one that works, some of them are just jam-o-matics. Mine worked great when I got it, then came winter. I tried shooting it in the cold and couldn't get a mag through it. I figure 'what good is a fair weather only survival rifle?'. No good at all.
A rifle with a similar overall design and configuration in a manual action, maybe a bolt or maybe a single shot break open like 45-70gov suggested, would be a great gun.
