I recently bought a 15-2 and the rear sight windage screw will not move in or out. This sight version has the adjusting screw on the right side and another screw of some kind visible on the left side. I soaked the sight assembly in Kroil for many days and still cannot budge the screw. Is the left side screw a locking screw? It does not turn either. Perhaps there is a special tool for the left side screw? I have not been able to find a good detailed illustration of the parts for this sight. It would be helpful to have one.
Does anyone have any suggestions?
Thanks much.

According to the exploded diagram in the owner's manual here…

…#55 is the windage screw retainer, so that's probably what you're seeing on the left side. I don't think there's anything that locks the screw in place from turning, so maybe it's merely rusted.
Wait for other folks to chime in, though.

I had one that was rusted solid--it took a good soaking and a LOT of very tedious back/forth with the adjustment to get it broken free.

You may want to flush it with wd40 or another penetrating oil. It took me a couple of weeks to free up a bayonet on an old japanese rifle. I had flushed it a few times with wd40 hoping enough rust would come out to free it. Thought it was a lost cause but I finally got it.

This, especially the easy back and forth over and over. Also apply a little warmth, maybe just from a hair dryer to help the oil penetrate that little extra bit.
I went to a bookstore and asked the saleswoman "Were is the Self Help Section?" She said if she told me, it would defeat the purpose.

Thanks to everyone for the suggestions. I'm not going to give up on this sight. It's soaking again and I'll keep working on it. I'll let you know how it goes. https://www.danwessonforum.com/wp-content/forum-resources/forum-smileys/', '

Get a bigger hammer. Just kidding of course. Be persistent, it will come eventually.

According to a discussion we had quite a while back and some thorough research by a member, the best solvent type compound (and the best lubricant for storage) is a mixture of 50% ATF and 50% Acetone.
I've tried it.
Works for me -- maybe it'll work for you.

Thanks. That was the only thing I could think of but didn't want to appear even more silly if it was wrong.

When somone posted the published test results showing that the AFF/Acetone mix was far and away the best, I switched too. Anyone want a bunch of "Gun Lube"?

It took a while but here's a picture of the various parts for the windage portion of the rear sight for a 15-2. It's not the best photo, but you can see that the round nut on the left side of the parts looks like a miniature barrel nut. I think this part is called the windage screw retainer, because it goes on the end of the windage screw and it appears to be held there by pressure from the split end of the windage screw. It seems like there should be a special tool for removal & installation of this nut, but I have not seen any reference to one.
The windage screw is a familiar allen head screw, except that the head has ridges ("detents' may be a better term) on the outside. The little ball bearing rides in these ridges and serves to hold the windage setting. The spring and small bar with pointed end provide pressure on the ball to help maintain the windage setting.
I did get mine apart and back together, but even after much cleaning and smoothing I could not get it to work. I think that it was stuck in one place so long that holes rusted into the head of the screw and when it is turned to that point the ball jams it tight. I will say that reassembly is very tricky and can easily result in lost parts.
My next step will be to try to purchase replacement parts, but there is no hurry since I found a nice Millet rear sight on ebay. I would be very tempted to just buy a complete new rear sight assembly rather than try to repair the one I have.
Hope this info helps someone!
