Best optic mount

[Ki6vsm]

Thank you! Looks like 30 mm ring size. Looks like needs 8 mm clearance from the bottom and I think 1” from center so 1” offset?

You won't find a mound for that rifle with such a low height off the rail. Figure 1.5" off the rail, or slightly higher. Most of the mounts you're looking at are ~1.5" high to ~1.9" high.

Not QR. I like BUIS for everything. I have them on my AR with red dot and magnifier and on my pistols with red dots. I assume technology will fail and I always like iron at least for backup.

I hope you aren't expecting to be able to use standard type BUIS without first unbolting the scope from the rail. Your scope (any scope) is going to overhang the rear BUIS and prevent you from flipping it up into position.

So, you'd need to switch to 45-deg offset irons if you want to keep the scope mounted on the rifle AND be able to use the irons as an option.
