There was some detailed instruction on tighting the rear site windage on a 03, mine has just a little play/slop R/L anyone have this info. The threads on the windage screw and the threads on the leaf look clean and sharp. Should I just replace the windage screw and hope for the best? The spring does feel firm.

I doubt that replacing the windage screw will correct your problem.

As you perhaps may have noticed, the windage screw has a coil spring underneath the collar on the right side. The coil spring is responsible, among other things, for removing the side-to-side play.

The windage screw has a beveled head on the left side, which sits in a countersunk groove on the base. The coil spring pulls the beveled head against the countersink to engage the screw threads and remove all side-to-side loose play. If the beveled head bottoms-out in the countersink, however, then loose play can develop.

The solution is to shim the forward edge of the left-side countersink to move the windage screw rearward very slightly and re-engage the bevel. That should correct your problem.

Good Luck!

Ok, how do I do that its a pretty small shim were talking?

'Tis indeed a pretty small shim!

I've never done it before. But, I know that's what needs to be done.

You might try some aluminum foil tape. Aluminum foil tape is used for sealing up heating/air conditioning duct work and is usually available from your building supply dealer (Home Depot or Lowe's). You may have to put several layers to get the thickness you need.

Good Luck!

O.K. here is what I did and it seems too work pretty good I went to the local hardware store and picked up a 1/4x1/8x1/16 #60 o-ring from Danco inc. it fits into the cup and and rests against the windage screws shoulder and its tiny spring. I have big fingers so I had my kid roll the o-ring on.

You will need a third hand too get the windage screw under the lip of site base, the play/slop in the windage is greatly reduced, but there is still just a we bit of slack from the threads not being in complete contact, I may try some aluminum strips for that perfect mesh.

The rear sight should have no side-to-side loose play. But, don't forget that the windage screw is spring-loaded. Therefore, the sight can be moved side-to-side under spring tension. That's normal. And if the sight is sticky, windage can change after each setting.

Windage is properly set by turning the windage screw COUNTERCLOCKWISE in every case. In the event too much windage is dialed in, turn the windage screw clockwise for a revolution or so, then back it up counterclockwise to the proper setting.
