If you have multiple uppers in different configurations and you have a registered SBR lower, then the intent to construct should be satisfied with the registered lower, because you have a legal platform to put the uppers on. The problem with SBR uppers being around lowers is when the owner has no registered SBR lower to put them on.
Not as likely that someone who has gone through the process to register an SBR is going to wipe out his gun owning privilege for life by intentionally constructing an illegal weapon when he doesn't have to.
