Hello, I am interested in the experienced answers to this question. I have a Kalinka guick-detach side rail mounted optic rail. In true reality, how well will the sights return to zero after taking it off and putting it back on again? Can we try to be specific, because I was thinking of getting a second rail and mounting a regular scope on it. Then swapping as and if needed. If they don't come back to zero, that is a useless endeavor as is the QD mount theoretically. Thanks in advance for any learned tested experienced answers and opinions too. pascal Wanna kill these ads? We can help!
