Neat. I like the side mount. I picked up the dust cover scope mount from corwin arms a little while back (
https://www.corwin-arms.com/product/cz-858vz-58-dust-cover-scope-mount-2) and it's an okay mount. My only beef with it is that it requires a tool to remove/reinstall. However, I found it a lot better than the front foreguard mount (covering the piston).
I've used the side mount adapter and found the site mount way too high, the mount heavy and bulky. The advantage of the side mount is that the rail allows for easy swapping with other scope/bracket combos.
