I've used a set for several years on my Vari-X III 4.5-14 and they've worked very well for clicking to out past 1K. On this scope, the marks on the turrets are 1/4 MOA and the numbers are 1 MOA, so they work perfectly to match the clicks on the scope. They aren't made any more, but if you can find them and they fit your scope as above, they seem to be a cheaper alternative. Mine were not designed to go outside of an existing target knob, but screw onto where the cap would've screwed on to cover the vertical or horizontal adjustment of the scope. What's wrong with the current turrets you have? Good luck.
