    I have gotten forms through listing multiple calibers. 9mm, .223, etc. I don't believe "multi" would work, but then I've never tried.

    When I did this I was registering just a sear. If you're building a AR for example in .223 and you later put a 9mm upper on it, I don't believe that will be a concern and it doesn't require you to list that caliber on your Form 1.

    I could be wrong, the people to ask would be the ATF.

    You're right. I know of several people that have had to correct Form 1's lately for listing mulitiple calibers. As Full-Auto said, once you have the approved Form 1, you can put another upper on it of what ever you want. The ATF asked that you notify them of a permanent change, but that's not even required.

    Thanks. I had a friend clear it up for me, too. The answer that seems most correct is: You put down the caliber of whatever you're building. You can swap uppers later and as long as you retain ownership of the original upper, you don't need to contact ATF. The reason for my question is I have a lower marked "multi".
    Thanks, INGO!:ingo:
