For those devoted to the AR, your choices for new manufactures would be a choice between featureless or top-feed into a fixed magazine. As for various tricks and workarounds on the issue of detachability, be careful and keep in mind the many failed efforts by California 2A hobbyists, and my one simple adage: "If you think you've gotten around a gun law, you're probably in violation of it." In a lot of restrictive States, all it takes is a word from the attorney general for some such thing to hit the ban list.

See also TDF 57 for videos by California law enforcement officers (so take it as you judge) on ban-beating arms. The first video discusses a bullpup design, and I have to wonder how long till those are targeted. The second focuses on the above weapon. Again, take it as you judge.
