Our friends over at Soldier Systems Daily got some gouge on good authority that terror mastermind Osama bin Laden was killed with a novel new weapon that's only been talked about in the shadows of special ops and the advanced carbine world.
"A very good source" tells SSD that the double tap to UBL's grey matter came from a Colt CM901 carbine chambered in 7.62.
We had the chance to see the CM901 up close at the 2011 SHOT Show. It's an impressive modular weapon that uses a gas impingement operating system.
Kit Up! also heard from a reliable source that it was Gold Squadron who conducted the primary attack-- DEVGRU's premier assault team -- and that operators were also likely carrying the Heckler and Koch MP7 submachine gun chambered in 4.6x30mm.
