The last two sets of Burris 'Zee's (supplied to me by their owners) were not anything I'd use or install. I showed them the areas of concern and both opted for different set ups.
An earlier set of 'Zee's (2003-ish) I now have on a 22LR are much better, with the exception of the cross bolt screw not being a Torx config as these later ones are.
My 2 cents worth, FWIW.
Good shootin' -Al
