Hmmm. It strikes me that, perhaps, the intention here had to do with so-called "assault rifles", even of C&R AGE. Since I've not heard of ANY talk regarding restriction of non- semi auto weapons (such bolt actions)..... I think the statement is being misinterpreted.
In any case, all of this is nothing more than massive speculation - with NOTHING to back it up.
But oh, I forgot, the "secret agenda" of taking all guns trumps all, right ?
Paranoia never sleeps......
