This is what the guts of the Whisper moderator look like;

The barrel on the whisper has 5 holes drilled in each flute on the barrel portion that is covered by the moderator shroud. An aluminium tube fits over the barrel and extends about 2/3rds of the way down, then there is a large thick washer and spring. On firing, the holes vent the gasses which are then directed down the flutes towards the muzzle by the aluminium tube, into the expansion chamber which comprises of the large washer and shroud end cap (the spring seems to be there just to keep the washer in place).
