I've gotten screwed over on an epic proportion. I was looking into buying an AR15 for myself at the end of November. I decided to get separate upper and lower receivers, to customize it for myself a bit. Bought a Daniel Defense upper at the beginning of December and was waiting for a Spikes lower to come in stock at Brownells. Well, didn't realize that panic buying would ensue, so now I am stuck with a lonely upper receiver and no way to finish my rifle.
No panic buying here. It's just a shame that everybody has to freak out over this!
