Dang it, and I need an upper, too! I'd like to complete my AR someday...
Same here, I've got 2 stripped lowers laying around and a few parts on backorder, I'm just going to slap them together as I find deals on parts.
Remember a few months ago when a SWAT team accidently left a FA AR in a neighbors lawn after a raid? That would have been quite a find... I'm too paranoid though I would have turned it in.
As AJ said, I could probably get away with anything.. the key is not telling ANYONE what you have, or what you have done.
