I have all my diavari scopes with elevation and windage knobs ,their clicks are .36 and have the kenton speed dial knobs that get me to 1,000 in one revolution. zeiss will install for $60 a knob and ask for sonya she is great to deal with . the zeiss in the diavari with ffp has never let me down and ive used them on 338 lapua down. thanks anthony
