I'd not worry about AR mags.
If any of you had military connections in the ban years getting AR mags was quite the easy task. Around Bragg if you know the right people there $5 a pop for USGI mags as we speak. I've got 3 trashbags worth down there for that price if I want them and I'm not in any hurry for them.
You need to worry about non surplus mags like CMMG conversion mags or mags for comercial guns. Anything that was ever milspec will not be a issue.
