Update: It's a regular scope with something called Killflash mounted over the objective lens. Near as I can make out it is grid of narrow channels which ensure that the only light reaching the lens is coming straight in, or at a very narrow angle. The idea is to prevent sunlight from bouncing off the lens and giving away your location to the enemy. Its construction appears to be very similar to the innards of the catalytic converter you find on your car.
