My Krieghoff .470 came with the optional "see through" sights. The front is a large fiber optic orange/red bead which gathers light well. The rear is the outline of a rear sight, with most of the rear sight metal removed, so you just have the outline of the rear with an red/orange line leading up to the vee notch. The advantage is that the rear sight does not block your view of the animal, as you are actually "seeing through" the rear sight. Simply nestle the very visible front bead in the rear notch atop the red line and squeeze. These are the fastest open sights I have ever used, and the most practical. While likely not as rugged as the classic solid sights atop a rib, I have fired several hundred full charge loads through that rifle and it has accompanied me on six (6) DG safaris with no issues.
I believe they are made by Recknagel in Germany, but am not sure. You can probably contact Krieghoff to verify that.
Sorry I can't post a pic, but that is way beyond my technical ability.
