I got a new 3.5x10 Leupy with the finger adjustable knobs...and am very disapointed with it. They were not thinking of the LR shooter in mind when they designed it. The knob cannot be moved on the spindle. The zero adjust wanders around at random, i.e. it is not at the back. You have to search all over for you elevation & windage zero's, then squint at the poorly labeled knobs to make changes. I was WAY faster and more accurate, with the old system and a cartridge case. And, the **** knobs are made of plastic, so they cannot be remarked to work better. I hope that someone comes out with some aftermarket knobs for these scopes.
