Thought it again. I think I got it.
Not related with caliber. The rear sight height must fall into the range measured by the two heights. It cannot be exact, must between 6,64 - 6,7. One height must higher than the rear sight, and the other height must be lower than the rear height. So the rear sight won't be too high or too low. Manufacturing tolerance was 0,06m/m. |
