Sights Will Not Adjust

[Rainman1977]

I bought a Mark III Hunter a couple of years ago and never tried to sight it in until now.

The screw turns and clicks, but the sights do not move. Twenty clicks and the bullet hits right where the first one did.

Help?

Call Ruger with the serial # & ask nicely & you may get a replacement for FREE..
That's what I'd do..
Worked for me before..
Lucky for you it's a MKIII as that's all they have anymore..

Sounds good.

Does anyone have an estimated cost for a gunsmith repair to the sights?

If you can get the set screw loose & get a drop of oil down in there the entire sight will drift out with a brass punch & a hammer with the barrel clamped in a padded vise.
Just as easy to replace & tighten set screw..
Call Ruger & get the sight coming your way..

I will call Ruger, but I'm am a bit unclear on how to remove and install the new sight. Do you think they might have some drawings, pictures, etc covering the process?

Page #41 of the MKIII Manual shows the sight assembly pretty well, You can view it here.. You can also increase the size so it's blown up in this PDF Format..

When you say the sights do not move, do you mean not at all or not in the direction you are try to get them to move in?

If it's the former, some thing that come to mind are:
The sight is frozen/dirty; try a little a cleaner/lubricant on it.
Elevation screw not seated properly or not in it's hole in the sight base.
Broken spring or stripped screw/assembly: requires replacement of damaged part.

If it's the latter, you are maxed out in travel that direction.
To correct for windage, you need the center the rear sight blade and move the entire sight assy. left or right and try adjusting again.
Elevation will require more effort to correct: ie. replacing the front sight, replacing the rear sight blade, removing material from the front or rear sight, etc.

The gun is clean and has never been dirty as I bought it new and seldom used it. The travel, once maxed out, will stop. I went both directions in evelation. I did not try windage as the height was off a good bit and the windage was fairly close.

Here's the Image of the Rear Sight Assembly from the PDF Manual @ Ruger..
The Center Screw or the housing must be stripped out..
You can see the Set Screw #16 on the Left Hand Side, Loosen it with a Small Flat Blade Screwdriver & Drift the Sight Assembly to the Right with a Brass Punch & Replace with the New One Toward the Left..
Have you Called Ruger Yet??
Good Luck!!
