Need Tech Help With Rear BUIS

[davidjinks]

I’ve just discovered Scalarworks PEAK 02 BUIS. (I’m sorry KAC, I’m leaving you for someone else!) but I still love you and you will always have a place in my heart!!!

Technical question: I purchased the PEAK 02 1.57” rear BUIS. All of my rifles, sans my SPR, have an F marked FSB. Will there be any issues zeroing my irons while using the 1.57” rear BUIS?

EDITED TO ADD:

These are some of the lowest profile sights I’ve used so far. I like the fact I can change aperture’s on the rear sight as well. The cost for a set (Front and Rear is what a KAC rear sights costs).
