Installing new rear sight blade

[skeeterbait]

OK, Model 60-15 3" adjustable rear sight. I have the new white outline rear blade, I have the spanner tool and the punch kit. I understand the process of breaking the bolt, retaining the spring and detent. Have read the instructions and watched the Midway video on doing this. One part is not clear to me. Staking with the punch. Is my intent to slightly swell the end of the bolt so it will not back out of the nut? That seems logical to me but it does not say in detail.

Yes. Place the head of the windage screw against something solid (like a hardwood block), put the punch in the other end and wack it. Tighten the nut just enough to take the endplay out of the sight blade first. Do it just right and the windage screw will have a little more drag than from the detent alone.

Great, thank you.

Be cautious with the "Wack" it. I use a 2 oz. ballpeen hammer, and just tap it to swell the end out and hold in place.

A tiny dab of Loctite 242 works just as well and is much easier to do with precision.

I LIKE that idea. Probably removeable and reinstallable. I will try that first and see how it works out. Thanks!

On mine I drill the end of the windage screw (3/32" bit) to remove the swelled section and reuse the screw and nut. I put a small amout of 290 Loctite inside the nut so it can wick into the threads. I got tired of trying to get the endplay on the sight blade just right. The endplay tightens when you swell the screw end. They were usually too tight or too loose and I'm fussy. But that's not what you asked.

Yeah, didn't know to ask, but I'm learning. Thanks again guys.

A tip that I will add is that it comes time to slide the windage screw amd sight blade out, you need to put the gun and your hands inside a gallon size zip-loc bag. That way you will not loose the teeny tiny detent plunger and spring that sit in a hole in the head of the windage screw. Slide the windage screw out slowly and carefully and you will see the shiney silver head of the detent plunger and you'll be able to capture the little devil before he rockets off into gun part oblivion. If it gets away from you, not to worry it's somewhere within the confines of the zip-loc bag. Try this trick, you'll be glad you did. BTW the trick is not original to me, I learned it here on the forum. I'm just passing it along.

Yes, yes, yes. When you buy the sight blade it's worth getting a plunger and spring too, just in case.
