I should make a small correction. The Z6 scopes are either .36" or .18" (higher mag models). I suspect the lower powered range will be different again.

Looking at some varmint scopes currently.. Z5 5-25x52BT 4W .25"clicks and/or Kahles K10503, 6-24x56 with FCH 1/8" clicks.

If anyone has compared the two I am all ears.
