I stumbled on this because nothing else was working. After going through six weeks' worth of getting notifications from Midway USA and then once you get to the website they're out of stock, over and over, and Brownell's was perpetually out of stock with no notification to waste your time, I tried this: Here's the long story: A little while ago I went ahead and placed an order @ Brownell's for some Magpul 20-round AR mags, got the "this is out of stock, what do you want to do?" pop-up... chose "add to cart and backorder" then completed the order through checkout. Got their usual email "Web notification" which detailed the order and advised that the stock is on backorder. OK, so far so good. Checked credit card next day and no charge on there. Good. Here's the good part, about a week later, bang, here comes a shipping notification, the mags are on the way! On the website they are still "out of stock" but they are shipping these things!!! :redspot: YMMV, but this worked for me (relatively) immediately. *Here's the ADD short version: order through "backorder" at Brownell's and they don't charge your card 'till they ship, and they are shipping, even though it doesn't look like it! Woot!
