Error in Kuhnhausen Shop Manual

[ssgross]

Also, the sight alignment spec is said to be max of 20' (minutes) of true. Seems a lot at a glance. If I had sight height and radius in hand I wouldn't be able to resist translating that to downrange impact.

I was way wrong. It's nothing at all.
Sight height spec is 0.728 - 0.005
Sight radius is 29.5
So 20 minutes rotation gives 0.0042 lateral displacement of the front sight
This gives a downrange error of 0.522 MOA from true.
