Got the front screw loose. Not really slotted, was able to level it out some, if you notice in the picture above it slightly slanted up on the brass bead side. It only lowered it about 0.005", not sure if that's enough but it does look level now.
I can live with it but the rear sight is up off the fine adjustment screw so when I loosen the locking thumb screw on the side it can't be adjusted with any precision.
