Well that would defeat the purpose of the rail since I was looking for something that would allow me to still use my BUIS.

Raising a 3-9x40 high enough to use the BUIS will result in height over boreline issues.
You might as well be mounting it on top of a carry handle.......height would be the same.
You would be much better off just mounting the 3-9x40 in QD rings and removing it quickly if it goes TU.
