I have recently bought a NIB CZ zkk-601 in .243 Win. It has rail for mounting scope I intend to find a Redfield Revolution 4-12*40. The rear rail has a niche on the left side which seems to me have been made for locking the rail but I have yet to see a pair of rings which fill that niche. Can somebody help me by telling me the model and make of rings made for this type of rail.
THANKS
