At least in Texas, the AR bought now for 400 bucks would likely be $4000 6 months into the ban. That seems to be the way things go regardless of laws. Just look at how class 3 firearms have escalated. Even if the AR is technically illegal to own, it'll gain value. I look at the Klinton gun ban. ARs with a bayonet lug were 4 times the price of one that complied with the laws. Heck, I'd sell my M4 in a heartbeat and just buy a compliant gun if someone just HAD to have a bayonet lug. I don't need no stinkin' bayonet!
