Adjusting sights on a Mini 14?

[zxcvbob]

My new ranch rifle shoots several inches low with the iron sights. (the windage is right on) So I got out the owners manual to see which way to turn the adjuster -- it says you need to loosen one of the windage screws first (just one so you dont lose the adjustment) and then turn the top screw in 1/2 turn increments to raise and lower the aperture.

I did that, and the aperture doesn't move. I think the aperture is all the way down, and I can't turn the top screw clockwise. When I turn it counterclockwise, the screw unscrews but that's it. What am I doing wrong?

You actually turn the aperture, not the front screw. You should be able to rotate the aperture and make it go up and down....

That works so much better. Thanks.
