I bought a peep sight for my CZ 550 FS. Unfortunately the stock front blade is too short. The fiber optic one I bought is also too short. A bummer because it took a while to file and fit. I recently ordered the tallest OEM blade I could find, waiting for it to arrive. Wondering if it will be weird using it with the front hood, but it looks quite fragile so hunting without it would be risky I think. This chunky sourdough post looks quite nice. NECG makes them. Should have ordered one when I bought the peep… Can’t wait for my setup to finally work!
