I just used "DFM" at Brownells to buy a Spikes Tactical upper receiver that I was surprised to see in stock: http://www.brownells.com/.aspx/pid=4...eiver-Assembly
At the time I added it to my cart, it was in stock. Then while I was browsing around, I saw it was OUT of stock. I hurried up and finished my order (saving $50 with DFM!) and it finished the order, the invoice says "in stock". I don't know though, kinda worried.
Edit: Backordered, DAMNIT!
