Rifle Scopes Setting Windage on USO SN3?

[bubajoe]

What’s the proper way to zero windage on a USO SN3 scope? The scale behind the knob starts at zero on the left and goes 6 on the right in MIL increments with 1/10 mil on the knob. This is unlike other optics I own which have the zero in the middle and work out in both directions.

Re: Setting Windage on USO SN3?

that scale (0-6) shows you how many complete revolutions you have turned out the knob. One complete revolution will expose another line (or hide it if you are turning it inwards).

To zero, just zero the rifle and loosen the knob and spin it to "0", line it up and re tighten. You use the underneath scale to keep track of complete revolutions.
