20 minutes video...care to just post the list?
No kidding, I checked out after two minutes of yapping and hand waving. No patience.
They covered much more than just 5 guns. From what I recall:
Short Barrel Rifles
2 Bull Pup style Rifles
Anything with large capacity (may be normal capacity) detachable magazines
Modern combat-style semi auto shotguns
Any assault-style rifles like M1A, FAL, etc
