Well as much as u may disagree with it..... It's the way the Soviet Union had designed most of their rifles to be optic mounted. Considering they utilised the system for many decades, they obviously thought it worked quite well. And many users of the combloc firearms still think so to this day. Like u said, it may still work great, but on a Combloc gun, a handguard mount will always be a retrofit compared to an integrated side mount.
Agreed, works great for magnified optics but you also didn't see a lot of Aimpoints in the 50's.
