Someone ...

... has tracked AR-15 prices:

What’s really interesting is how there are two peaks in the price; one a few weeks after the panic started and another after president Obama announced his support for an assault weapons ban during the SHOT Show. In general, though, the trend is a downwards one. People seem to be running out of money and supply is starting to catch up with demand. The incoming flood of tax refund checks will keep things hairy for a bit, but the worst may well be over.

That's good news.

I've noticed in my post-Dandy Hook Shotgun News that there doesn't seem to be any real lack of lowers. Some of my connections are finding it hard to find uppers, however.
