Not a gun writer but I have one I've on a CZ 527 carbine. What TheKid said, it, required a taller front sight for the CZ too. It looks to me like quality machine work but. IMO the adjustments are comparatively coarse when compared to say a Lyman, Redfield or Williams receiver sight. I'd say they would be fine for a closer range eastern deer/woods rifle and clamp onto the receiver securely with no drilled holes required.
