Educate me, please.

I'm sure this is simple, but right now I'm stumped.
Mainly 'cause I'm just not experienced at this sort of thing.

I just had a good smith install a high end scope on a modest but good shooting rifle.

The scope is a Swarovski Z6, the rifle is a CZ 550.
I supplied the smith with CZ mounts.

Yesterday I took the rifle to the NRA HQ 50 yd indoor range.
After a fair amount of fiddling and head scratching I understood that the
rifle is printing very tightly indeed, albeit 4" low at 50 yds.

I cannot further elevate the scope as it turns out it is maxed out on elevation.

I just don't understand how this can happen, other than some gross dimensional
variation in the mounts which have the scope at a cant.

But the smith is a thorough guy, and I have no reason to doubt that he did as he was supposed to do.

What gives?
What do I do about it?

Diagrams and illustrations welcome!

    While I know nothing about CZ mounts specifically there are some rings that are front and back specific. Try switching the ring positions and see if that helps. If not you could try a tapered base or Burris Sig. rings with the inserts.

    The back mount on a cz has a extra tab on it. I don't think you could mix them up. Have you had a dif. scope on it in the same rings.

    I had a cheap 1" scope on CZ rings.

    It set up easy, shot well right off the bat.
    I decided to upgrade the glass and here we are.
    Don't I feel an ass.

    Will look for that tab.
    Don't recall seeing such a thing.

    I had already been looking at the Burris rings with the Posi-align.
    The 30mm Zee look like exactly what I need.

    The only bit am missing is what size that base is designed for.

    Anyone know?

    The CZ 550 "Dovetailed Square Bridge" is 19mm.
