Findings
of yours are about the same as mine. It appears to me that this system is basically sound but we need something like a Tactical Knob maker to , pardon the pun [ but cant resist] "come up" with a click stop type modification in which under low light the shooter could click down to the( adjustable) zero then just listen to the up clicks as in the old Redfiield iron rear sights. Anyone reading this who has the ability to make this happen? The Ivy adjustable base is the ideal vehicle for one unit to work well as it only requires one knob. Many thanks, Overbore
