It appears to me that this doesn't actually change anything. The surprisingly good news is that the ATF views tube and detachable box magazines as equal; they are only concerned with capacity, so this document doesn't bode as badly for the Saiga as we had feared.
It definitely highlights the ridiculousness of some of our laws, and the idiocy of our politicians. I especially liked the quote from Chris Dodd.
I was shocked that they actually mentioned possibly considering USPSA as a sporting purpose, although they decided it would need further study.
All in all not as bad as was feared when the news broke over the weekend. I guess the Prince Law guy is finally vindicated somewhat.
I will add that it is a little scary to see so much movement in the anti-gun world at one time. Nationally, it has been a pretty easy decade or so, but now we have ATF getting a new, anti-gun director and issuing "studies", rumors of the POTUS calling for new restrictions, and even prominent GOP elitists calling for magazine restrictions. Circle the wagons, folks. We need to build on our pro-gun gains in 2012.

ATF said:
On the list of 10 "disqualifying features", one really stood out as odd to me:
(1) Folding, telescoping, or collapsible stocks;
(2) bayonet lugs;
(3) flash suppressors;
(4) magazines over 5 rounds, or a drum magazine;
(5) grenade-launcher mounts;
(6) integrated rail systems (other than on top of the receiver or barrel);
(7) light enhancing devices;
(8) excessive weight (greater than 10 pounds for 12 gauge or smaller);
(9) excessive bulk (greater than 3 inches in width and/or greater than 4 inches in depth);
(10) forward pistol grips or other protruding parts designed or used for gripping the
shotgun with the shooter’s extended hand.
The other stuff is all evil features from AWB of old; what the heck do they have against rails? I mean, I think modern guns are way over-railed too, but why is having a convenient mounting spot for a light un-sporting?
