I got a new to me WOA NM A2 upper sighted in today. Need some help as this is the first NM-type upper I've used: + What is the per click angle on rear sight windage? How many MOA per windage click? + What is the per rotation angle on front sight post? I don't know if this thread is finer than a regular A2 FSP. I have a tapered 0.052" FSP, so it only times once per full rotation. How many MOA per rotation? + I think rear sight elevation is 0.5 MOA per click, correct me if I'm wrong. I am roughly sighted in at 100yds but I'm about 1 MOA right (the rear is mechanically dead center) and 1/3 MOA high, I don't know the best way to adjust dead center. Thanks. |

The front sight gives a little less than 5 MOA per revolution. WOA uses, or used to anyway, an elevation wheel that was 1/2 MOA on one side and 1/4 MOA on the other. You could disassemble them and have it whichever way you like. Windage was either 1/2 or 1/4, depending on how you ordered it. |

Thanks both of you. Damn I didn't even notice those set screws, good call on the website, should've read that before going out. Rear sight is pinned. |

Most sights are 1/4 x 1/4 or 1/2 x 1/2 Front sight full rotation is about 1.75 moa if I remember right. NM front sights are generally sloped so you have to go full rotation up or down. I've always come up 2-3 min from bottom on rear and adjusted front for 200 elevation zero. |

You probably can’t adjust to dead center windage without rotating your front sight base, which is a laborious and hit or miss process when you’re that close. I think you just have to accept mechanical zero is two or four clicks left depending on click adjustment. Same with elevation, |
Ellen; Clark, I think it'd be best if everyone went home... before things get worse.
Clark; WORSE? How could things get any worse? Take a look around here, Ellen. We're at the threshold of hell.

| Just remember when setting mechanical zero move the front site toward the strike, a small rubber mallet can be useful in getting/keeping the site flush against the set screws when making very small turn adjustments, 1/8 turn. If you can get within 4 clicks you've done pretty well. |
