    Ok... Since every one of the three Williams FP (foolproof) sights were bought used, or came along with a used gun.. I have no instructions, nor are there any on the Williams website that I can see... so...

    2 questions (my gun is shooting approximatly 2 inches low at 25 yards..)

    1. Which direction do I move the elevation adjustment to bring the POI UP??

    2. Each click on the williams is equal to how much adjustment at 25yards (or 50, or 100: any of the above would be helpful.)

    Thanks so much,

    I don't remember if the elevation and windage screws are right hand threads, or as those crazy Redfield Olympic and Internationals, left hand threads.

    It is easy to determine. My Williams has a slide jam screw that must be loosened before attempting to adjust the elevation. Once that is loosened, turn the elevation screw clockwise, counting the clicks. If the slide raises in the base, then you know it is a right hand thread. If the slide lowers, than remembering the clicks, click back.

    These sights were quarter minute clicks. This means four clicks equals an inch at 100 yards. Eight clicks means an inch at 50 yards. 16 clicks equals and inch at 25 yards.

    So click up 32 clicks at 25 yards.

    Then check it out at 100 yards.

    To raise the point of impact, turn the adjustment screw counter-clockwise. There are locking screws that have to be loosened before moving the adjustment screws. They are the two little screws that face you as you are looking through the sight. The left one locks the elevation adjustment screw, and the right one the windage adjustment. Loosen them a quarter turn, no more. The big screw on the side with the shiny bushing around it also needs to be loosened when adjusting elevation. So, loosen the locking screws, turn the adjustment screw, tighten the locking screws.

    They say that clicks are approximately 1/4 minute, depending on sight radius, so two inches at 25 yards would be 32 clicks.

    You reminded me to go look for this information . . . I put my spare front reticles in a tiny plastic pill bottle to keep them safe in my range bag.

    Hope this helps.
