Here's a link to a company that sells adapters allowing 30-06 and.308 rifles to be temporarily adapted to 7.62x39 ammo. They also sell several other adapters.

When NATO went to .308, adapters that allowed M-1, M-14, etc. to shoot .308 were available. These used to be dirt cheap, but I haven't seen any for quite a while.
For me this was an idea whose time never came. I don't like it, but it's worth knowing about, particularly if you run across a gun with one of them in place.
