Not my claim. Remember, I think some of those non-banned weapons should in fact be banned.
Beats me. I’ve never examined, much less fired, a Ruger 14.
Nor should I, considering I am wholly unfamiliar with the Ruger 14.
I believe I described it as “a step in the right direction,” though it obviously leaves much to be desired.
I have not defended the details of the act, apart from calling the gun fans on the “cosmetic” crap. What I have defended is the concept of banning assault weapons. I’d be happy to do so with reference to the features you described above. But I assure you, we’d still be having this argument even if the statute were as conceptually clean as a whistle on a drawing board.
That’s what kills me about this. You guys don’t want any meaningful restrictions at all on these guns, yet you obsess over the details of the ban. “Oh my,” the gun fans cry, “this definition seems silly and leaves closely similar weapons untouched! What horrible legislation!” As if you’d be happy if the ban was improved to eliminate all the loopholes and barely-missed weapons. Very amusing.

Turns out, though, that that one little exponent is crucial to the discussion. Because energy goes as mv[sup]2[/sup], but momentum goes as mv[sup]1[/sup], it’s possible to raise the energy while lowering the momentum (or keeping the momentum the same) by raising v while lowering m. Which is what the .223 rifle cartriges used in the M-16 do.
