Probably not, but I don't think the adoption or avoidance of an item by government bean counters is a good litmus test for whether something is useful or not.
Phase 3 malfunctions are a great example of an administrative action made easier by a BAD lever. Anything requiring you to lock the bolt to the rear will be made easier with a BAD lever, and keeps your strong side hand where it needs to be on the rifle.
I originally tried one of these, but it was causing my rifle not to lock back on the last round, so I swapped it for the Magpul version instead. I couldn't say why it happened, but it did.
Again, I think that's a training issue. Your finger should be bladed along the side of the receiver until you're committed to your shot; if someone's finger is in there prior to that then it's their fault, not the BAD lever's.
