You need to use the "page updater" add-on in Firefox. I've added all the 556, 22lr, 300 blkout, and 9mm I need the last couple of months. Find your favorite ammo pages, set the updater for all changes and to check at 15 min intervals. When a product changes from out of stock to in stock, you get a ding and pop-up alerting the change. Then, the change is highlighted on the page. Also gotten mags and three AR uppers the last couple of months. Gunbot is decent too.
