Am I crazy or has anyone ran into a Krinkov AK with the dust cover with flip up sights AND a side rail mount, BUT you cant slide a side rail mount onto the side rail because it interferes with the fixed flip up sights on the Krinkov dust cover? Why in the world was the side rail mounts designed on the Krinkov is my first question, and when in the world would anyone use the side rail mount if you have to change out the dust cover for something like a TWS dog rail anyway?

Literally my face last night figuring this out for the first time. --->

There are some side rail mounts that have a rearward bias and shorter optic mounting surface that will position behind the rear iron sight parts.

Just ordered one. I had no idea what they were called. Thanks!

You picked the name krinkovovich without knowing about AKSU optics?



This is a good resource to see what Russian optics that were meant for the AKSU looked like and why they worked with that receiver cover:

A rear based RS Regulate or AK mastermount should clear it.
