CZ/FAB Rail extension idea

[1965BJS]

I have the FAB defense polymer handguards, was thinking how it would be nice to have a rail that could extend back over the dust cover, i think there is an Ultimak rail for the AK's that kinda does the same thing. Is there a type of riser that can be purchased that can accomplish this?
I like the Beryl type of rail that the AK boys can get but nothing similar is available for the 858 is there?
Nea cantilever mount is pretty close, but I don't want to have to re purchase the buttstock as the one I have is FAB also.
I'm just looking to put some magnification on the rifle without having to go side mount.

Untill some company comes out with the "Beryl type of rail" there is nothing that fit's your bill. Although I would strongley recomend the NEA 1 even if you already have a rear AR stock adaptor. It's perfect for my magnification needs as you can see;
