The Skunkworks guys wonder...
I don't know on the barrel but it's a definite no on the bcg. Otherwise it would be about the same length as an ar with the stock collapsed. It also ejects down and out the back of the butt of the rifle. An ar BCG would have to travel inside of the shooters body to pull that off. It may be an ar bolt though.
