Recknagel also make different height bead front sights. The standard CZ bead is 6.3mm tall, and the Recknagels go up in 0.5mm increments from 6.5 to 9.5mm, if I recall correctly. They also make a 10mm tall post. The Recknagel beads are larger than the CZ standard and available in different colours.

When I fitted the NECG ghost ring to my CZ in 458, the standard CZ bead was spot on, but I needed a taller front sight on my CZ in 375 (it shot high with the NECG and standard front bead).
