Well, that was a bummer. I found the packages, but inside were A2 flash hiders. They're either still on the rifles or I sold them a long time ago. Sorry for the false hopes.
That's the good thing about paper forms. They mail them back with a collection letter. eForms they just deny them. I've experienced both in the past few months. There is the off chance they don't notice it and approve it. That's happened too.
