My wife ordered mine back in December...it was supposed to be a birthday present for me. After about a week of no update she started calling once a week, every time they said they were out of stock (black, large, with no d-ring) and had no idea when they would be back in stock. Finally, in January (past my birthday), she called and they finally suggested that if we upgraded to the d-ring they could ship it out that day since they were in stock.
Years ago I also ordered an OCPC from them with some pouches...everything that was in stock shipped out the next day, but one item that wasn't in stock (a 7.62 triple pouch) never showed up at all...ever. Luckily they didn't charge for it at the time of the order. Even after about 3 or 4 months of follow up it was never in stock and I eventually stopped caring and calling and apparently that part of the order just disappeared.
Moral of the story...they are awesome - if they have what you want in stock. if you already ordered online and don't hear anything after a few days, call them. While on the phone with them, if your item is out of stock, actually ask if there is any suitable alternative in stock (such as one with or without a d-ring, depending on your specific order). If not, you could be waiting a LONG time with no updates (unless YOU reach out to THEM).
