Stubborn rear dovetail sight

[HJ267]

I have a JC Higgins model 45 which is basically a Marlin 336. I am trying to drift out the rear sight without much success. Drifting left to right. Brass punch and mallet. Put some Kroil on. Nothing doing. Words of wisdom or ideas? Thanks!

Use a hammer, mallet too soft.

Sorry for my lack of clarity. I have been using a brass hammer.

Put some heat to it, do you have a hot air gun or maybe sneak the wife's hair dryer out.
Then more Kroil oil after it gets hot.
Tap some more.
Repeat the above.

You have years of build up to overcome.

All right. I’m going to try that and give it some time

Make sure the gun is secure, and tap lots or whack harder. If you don’t mushroom the brass punch you’re being too gentle.

The opposite of heat may work too. I've put stuff in the freezer based on advise I got here. The stuck pins came out after that.

Sight pusher. Money well spent.

I wonder if touching the sight with a small piece of dry ice would quickly shrink it?
Gotta try that sometime.

Let the oil sit for 24 hours and work itself in. I always found that being patient works wonders. Lol. Even though I'm not.

Be a scientist instead of a caveman; put it in the freezer a couple of hours.

Just to be clear. Put the whole rifle in the freezer?

Cut it up into bite size chunks.

Seriously though, I would pull the wood off and put the whole thing into the chest freezer

Have not seen it mentioned but , is the rifle in a vise with padded jaws ? Flat on a bench or table allows for too much wiggle and misdirected force.

Any luck? Remember use bigger hammer don't hit harder with a small hammer. And use a short punch they make a difference.
