Ive got an A1 upper that I installed night sights on (XS).
The rear sight needs adjusting further to the left than the gun allows.
Im sure the FSB is not lined up correctly, so I have to knock the pins out and adjust it a little.

I would like the rear sight to be in the middle if at all possible. What diection should I bump the FSB?

I am gussing to the right
