I havnt got or used one of them to be able to comment on...
Its a bit hard to give an opinion on a "feel" that
you are experiencing...
If you shoot at a range, ask others if you can feel their knob for vertical...let them know you're insistent on them feeling your knob for vertical too...
Just walk up to them while they are shooting & ask quiety, with a discreet wisper in their ear..."can i compare the rigidity of your knob to mine with my fingers"--insist you'll be gentle & return the knob to the exact position it first sat......
Seriously though...while i joke, ask others...!!...try others....then make youre own assesment as to whether you send it back--the turrets should feel pretty much the same, so if one is vastly different to the other, so much so that you cannot be sure of click value, then maybe you should send it back...
The man who knows everything, doesnt really know everything...he's just stopped learning...
