scope mount

I had a similar issue with some Aero Precision backup sights. They were too tall while folded down to fit below my 1-4x SWFA. So I swapped them out for Magpul MBUS and put the Aero irons on my AR Pistol with Red Dot, where they would be out of the way.
OP - your options are:
1) switch your rear sight to a lower profile option (Magpul MBUS is pretty low for what it's worth)
2) buy a taller scope mount
3) ditch the backup irons altogether
