I'm new to rifles but I just got my black USC and it is a beauty! I have an EOTech 512 I want to mount on it but I'm not sure how to correctly configure it. I've searched and it appears the EOtech will not co witness with the iron sites...so does that mean that the red dot will not be aiming exactly right? If that is the case, what kind of adjustments do I need to make in order for the EOtech to be a completely accurate sight?
