There are small, white dots on the back of the elevation posts (side toward the action), seven on the Tall Post and four on the Short Post sight. On the top of the elevation nut there are four marks: three white and one orange (or possibly red), readily viewed in the elevation post notch. As you screw the elevation post up (clockwise), it takes two complete turns of the nut to move up one white mark. That means basically eight “clicks” of rotation get one white elevation mark. So, there are about 50 measurable settings on the Tall Post sight and about 26 on the Short Post,  before you run out of post.

     These calibrations are all equally spaced at .075” apart.  They serve to let a shooter return to a previously recorded sight setting for a particular powder measure, bullet weight, range or combination of all of these factors. They may also be used for re-setting when and if the sight is moved to a different gun.

     Windage adjustment is made by loosening the lower, smaller knurled nut at the bottom of the elevation nut. It only takes a slight turn counter clockwise to do this (and the elevation nut may not work with the lower nut loosened). With the lower nut loosened, the post, which is attached to the windage cylinder (calibrated and visible through the two overlapping holes in the  block), can be moved left or right. When the desired position is reached, the post and cylinder are locked in position by tightening the small nut back down (clockwise). With the lower nut snugged down the elevation nut will again function.
          With the post centered in the block, the peep should line up with the barrel sights. If it doesn’t, it means that the tang may be bent or imperfectly milled, or the barrel may not line up exactly with the receiver. If you plan to leave the tang peep sight on a gun with this condition, it is suggested that you shim the sight base so it does line up with the barrel sights. This procedure is discussed in the installation instructions.
