Interesting video but it's nothing that most us wasn't already aware of, from all the leaked photos of camouflaged mules; they field test the prototypes, in winter and summer weather, prior to it being approved for final development.
It would great if they WoWed us with some intel that no one else is privy to, like what kind of drugs were they on, when they greenlit that beaver-face front end, for the next M4..
