I don't think it's possible to patch up those policy demands and make them sensible either. The whole case for why rifle regulation is more important than handgun regulation and should be stricter than it - one of the key pillars of the current US gun control movement - relies heavily on the imaginary distinction between good hunting rifles and evil human-hunting rifles. Without that distinction, it's hard to justify the position that those guns should be banned or tightly restricted but not the handguns used by the armed guards protecting all the Hollywood celebrities cheering on gun control as anything but urban-vs-rural cultural warfare. Handguns cause a huge amount of death and misery in the US right now compared to rifles. (Of course, there's also some constitutional issues with taking those away... but that's another problem entirely.)
But actually none of this matters on HN. The interesting question HN is what the policy should be, not what the dumbest people in America advocating for that policy are saying. We're not actually going to impact gun policy at all here, so we might as well free ourselves to discuss it rationally.
Announce a ban on pink magazines to take effect at the beginning of next year, and sales of pink magazines will rise; American Rifleman will run articles comparing the effectiveness of various color choices; Guns and Ammo will have a feature on 20 pink magazines you should buy before the ban; and sales of colored tape will rise in two different ways: pink tape will be applied to drab magazines -- "less than 35% coverage, so it's legal!" -- and black tape will be applied to pink magazines -- "More than 80% coverage when inserted, so it's legal, but when we finally defeat the irrational ban, you can take it right off!"
The subtext here is yet another Firearms Policy Canard, which is that anyone who thinks semi-automatic rifles should be regulated must solely be reacting to the color of the weapon, and clearly doesn't know that there are farmers that rely on them to clear out smallish animals or whatever. Sorry, I get that most people don't take any time to research these topics, but they're in fact not that complicated (these are devices that were designed to be broken down and reassembled in a jungle during monsoon rains by teenagers), and I'm not cowed.
