Ruger .22LR 22/45 rear sight.

Okay, I got some range time again today and loved it, as always. I got the rear sight tweaked up and I'm shooting my best right now.

I remember one of my old guns had a fixed sight, but was bedded in a dovetail slot. I was able to give it a tap (or two) and move it a little closer to where my eye wanted it.

The rear sight on my MkIII is adjustable and it's sighted in. The sight itself is adjusted way over to the right, and the dovetail is way over to the left. The adjustment screw is hanging out the right-hand side about 3/16 or more.

Can I, should I tap the dovetail over to the right to center it up some, thus centering up the adjustable guide too? What should I use to insure no blue damage?

Also, there is a small setscrew on the top, rear, left-hand side of the rear sight. What is it for, how do I mess with it properly?

Wish I had a tad of web space to host a picture here and there. I'm ask Roadrunner if there is a spot.

Unfortunately the rear sight does slide around from the factory because of grease. I had a similar problem. Look at Bullseye's instructions for changing it:

You can take it out, degrease the dovetail, then get it back in. I just used liquid nails on mine to keep it in place, and used blue loctite on the locking screw.

You want the rear sight centered in the dovetail, then the rear notch blade centered.

Piece of cake. Centered, no DAMage and now I have to go back to the range to sight it in. That's what we call a win-win situation. Thanks melchloboo and Bullseye.

Just make sure you have set screw in good. I put a dab of liquid nails on each side of the dovetail.

I also marked the correct centering on the sight and barrel with a red nail polish. That way I won't wonder if its me or the gun that's off that day

Once you get it sighted at your competitive distances, consider marking with nail polish on the dials.

I Locktite'ed it on center, I doubt if it will ever move, I won't admit to using red

The nail polish sounds good for the side to side because I sometimes want a half of a click.

The red can be removed, just apply some heat and it will soften up the sealant. Red is what I use most of all.
