If you have waited this long to go AR, you may as well wait another 3-4 months. If the other posters are correct, you'll be able to just drive down the street and pull a nice unfired one out of the trash cans.(sarcasm) I hope some one begins to realize that people are not going to dump the rifles they paid over $1K for a month before. There's several months production already on back order for anything AR'ish.
I've sold most of the AR's I have decided to part with but I'll tell you, there will be 5 buyers for every AR that comes onto the private sale market for quite some time.
