The AK rifles are not precision rifles. Making them precision is an interesting project I am sure, but it is not their nature. I have an SLR with a QR dogleg mounted red dot. It returns to sub MOA (minute of adversary, or minute of animal) for sure. I am fine with that. If I ever shoot a money contest, I will click adjust ad hoc.
The optics mount will oscillate after the trigger is pulled, not while you aim. It will return to a steady zero when the oscillations subside. As long as there isn't any free play in the mount, it works fine in semiauto fire.
