I just spoke with the manager at my local Vault about some Flak Jacket 1.0 lenses that I'm looking for. He told me he had to go to the back to find them because they've been instructed to pull all of them because Flak Jacket 1.0 is being discontinued. They've already had to send back their custom frames to corporate. If you're into Flak Jacket 1.0 or you need XLJ 1.0 lenses for custom cuts (ahem X-METALS) or because you like Flak Jacket 1.0 get them now. You've been warned!
