For whatever it may be worth, neither the US Army or the US Air Force have upper receivers for the M4 carbines that are set up to use blanks without blank firing adapters. Strangely enough, the M249 (SAW) uses the same blank adapter as the M4/M16. Oddly enough, none of the weapons in the video had blank adapters. Of course, SOCOM could have ordered the special upper receivers from Hollywood prop houses and had them specifically for the rescue... Or it could have happened exactly as it was reported and the BBC's sources are full of [censored].
