Multiple SBR uppers on single registered lower?

    Ive heard that having multiple SBR uppers for a single registered lower on a form 1 is acceptable. The only condition is that the subsequent SBR uppers must have barrel lengths that exceed that of the originally registered SBR on the form 1.

    So if i register a 10.5" barrel on my form 1, i can buy other larger SBR uppers, for the registered lower, as long as they are greater than 10.5".

    Is this correct?

    It depends if you have other non-SBR'd lowers in your safe. This has been covered at length in other threads.

    I filed my Form 1 with a 7.5" upper which allowed me to then purchase other uppers and never really worry about the length,

    You can have 100 AR uppers of varying lengths all less than 16" provided you have at least one AR SBR lower.

    You can have 10 regular AR lowers in the safe with your 100 AR uppers and STILL be fine as long as you also have that one SBR lower.

    The barrel length as listed on your NFA paperwork does not restrict you to any particular barrel length. You can go shorter or longer as your heart desires. Same for calibers. If your paperwork lists a 15.75" barrel, there is no reason you can't go to 2.9875".

    Just to be clear, there is no such thing as a "registered lower." Either it's an SBR (with short barrel) or it's not.
