They're aren't exactly 90 degrees as you'd expect, you're right, but since I'm bracing both sides of the rail there is scope to adjust allignment each side, so it isn't really an issue in my case. Alignment isn't an issue so far, bar the time required to dial it all in. Chasing microns is slow going.
