They've got 150 of them back in stock, and they're only $179.95.  Be warned, though, the name is misleading, it IS A DPMS PATTERN BCG, NOT ARMALITE

I have one of the NiB 5.56 BCGs, it's great.  I have their newer 5.56 "Reduced Friction" BCG, and it's damn sweet.  Right now waiting on one of their 5.56 nitrided BCGs, and I'm pretty positive it'll be just as good as the others.  I have complete confidence in what they're making right now - it's proved to be good stuff.
