I have a brno ZKK 602 actioned rifle which I am getting a set of QD scope mount/bases for.
Problem is that the catalog lists the mounts for a 550 action. Will these fit my 602?

These are neat looking base and mount sets, has anyone had any experience with them?

CZ 550 is the standard length action.
(corresponding CZ 600 ).

CZ 602 is magnum length.

So it will not fit (But only lengthwise).

after a bunch of internet digging and a few phone calls, I note that the 550 is the modern version of the venerable 602, dimensionally the same, but different safety, shroud, no pop up peep sight, and different trigger.

A closer look will reveal:

The old 600 corresponds to the 550

The old 602 corresponds the 550 Magnum .

So if you have a one piece mount for a 550 it will not fit a 602 .
If you have a one piece mount for a 550 Mag .it will fit.

If you have a 2 piece mount it will fit any of the types mentioned above.
They differ in length of the action.

thanks for the input
