I had to drill down a bit to find out what your beef with the AG was actually all about and I guess I'm still a little unclear.
Okay, before yesterday, a person in MA could buy a gun with a Direct Impingement operating system, or piston, or blowback, provided they complied with a list of guns banned by name, as well as avoided certain scary features.
Well, Attorney General Darth Vader took it upon herself to "alter the deal" and has now declared any firearm with the same operating parts as a banned weapon will now, too, be a banned weapon. Extractors & charging handles, even. Basically taking the model bans and expanding them into broad technology bans. Then has the grace to say she will allow current holders of to-be-banned weapons that they may keep them by virtue of her say-so alone. "Pray I do not alter the deal further" basically. Effective midnight that day (yesterday)
This change came out of no where with no warning in a newspaper op-ed rather than a proper bureaucratic rule change or law passage. Very strange given how well prepared the whole spiel is, suggesting some dark forces at work behind the scenes (likely Obama from the looks of it). It caught everyone off guard, to the point that gun stores were panic selling all their semi-autos so as to not be caught with illegal or unsaleable inventory, and announcing they would no longer be selling ANY semi autos.
So basically all semi-autos in MA are now banned, and all that is left is the collection of them, unless gun owners rally and remove the ability to implement this proposal from the AG (preferably along with her job & pension). There is a rally this weekend; be there if you live up there.
