At 25 yards they started off being 5 inches left. Elevation set just fine.

The design has them setting low and to the right of the upper so when the gun is rotated 45' for shooting, the sight posts are directly over the bore. This allows elevation and windage to set separately.

I also tried a second gun, BCM 20". Maybe both guns are canted, but I would be surprised with a Noveske and BCM.
