    List every calliber you plan on using when you register your lower. If it is already registered, you can request to add the calibers.

    At least that was what the examiner I spoke with told me.

    Ya and you dont submit it on a form 4, its not a suppressor. you submit it on a form 1.
    that is if you intend to assemble it yourself. if its already a built rifle then ya a form 4 is the way to go....

    As long as you KEEP THE ORIGINAL upper you register it with then yes you can use different uppers on one registered lower. I dont know about that bolt gun but I would assume as long as you kept that barrel length you registered it with, dont see why you couldnt swap out. I know a guy that couldnt afford to do two SBR's I told him to register one lower and specify he would also be using a 7.5" upper as well as a 11" upper. He did just that and the ATF approved him to use both and said you dont even have to initially say you will use more then one upper. just keep the upper you register it with..... did i ramble? im trying to be clear haha
