It liooks like it would place the optic right over the action on a VZ 58 type rifle that would cause some grief. I also checked out there website and did not see any info on a flat top rail either. Although I do like the ability to center it over the bore. Wonder who is going to buy 1 to try it out?
I am almost positive that this mount will be too low for a CSA rail.
I have a low profile AK mount, and it is 2-3 mm too low... The only way I could use it is on a regular CZ 858 with Kasat's side bracket.. And still I had to weld the rail higher on the bracket... I wonder if they could give us some measurements to compare..
Other than that it looks very good and light.
