Why is it that the main objection concerning gun control

[Recursion]

71. It's a one-test ban with most of the features from the 94 ban listed...

...but the only one of those that gun owners actually care about is the pistol grip (it makes the gun easier to control and so safer to use).

That's also the one feature that many people who don't understand guns seem to associate with a high rate of fire, I assume because the M-16 has a similar grip, and it's a very noticeable feature that wasn't present on guns (even automatic or semi-automatic guns) from 60 years ago (its design was in some ways as revolutionary as the AK-47's, and kind of illustrates the "US spends millions to give astronauts a pen that writes in space, while Cosmonauts used a pencil" dichotomy).

The other features remain things that nobody cares about for the most part, though at least the bayonet lug and threaded muzzle are off the list, but the barrel shroud is on this one, and that's entirely a safety feature and has no business being banned. The barrel shroud also occupies a huge place in gun control rhetoric, ever since Cynthia McKinney talked for 10 minutes about how important it was to ban them and then couldn't say what they were -- that's the "Shoulder Thing That Goes Up" meme you may see from time to time. (If you're curious, it's something that wraps around the entire barrel rather than just the bottom of it to keep a shooter from accidentally burning himself on a hot barrel.)
