On my Katos, I took that nose piece off and put a Radarlock nose piece in it's place.I got the black ones, but I actually returned them because I only got them as a contingency in case I couldn't get the rerelease. I also got them at the time because they were forbidden fruit (a month early).
They really are cool. My only complaint is the nose assembly is rather large, so it looked like a dark halo in the center of my vision if I paid attention to it.
