How to remove stubborn rear sight on Model '94?

[MD]

I just got this 1956 Model 94 and have been trying to remove the rear sight to clear the sighting plane so I can install a Williams rear sight.

I did the same some years ago to a 1974 Model 94 and a few taps with a brass rod drifted out the rear sight no problem, but on the 1956, it just won't budge, no matter how hard I try.

I hit it so hard it scored the brass punch.

I don't need to get it off, as I've put the Williams on and looked through it and the sight picture appears in between the wings of the buckhorn sight, but prefer to get it off.

Do I need to find a sight pushing tool? Take it to a 'smith? Penetrating oil? Apply heat?

Dovetail sights are tapered, sounds like you are hitting it from the wrong side and maybe driving it tighter in the slot? Apply penetrating fluid and hit it from the opposite side, it should pop out.

I have a 1953 vintage that I removed for a Williams peep sight.

I was told pins and other things are left to right to remove.

I went left to right, the same as on the 1974

Penetrating oil can't hurt...make sure the barrel is well suported on the opposite side so all the impact is going into the sight and don't forget to put something between the barrel and the part of the sight where the steps were that is now rubbing on the barrel.

bigger hammer, brass is softer than the steel. the part has not moved in over 50 years.

A small amount of rust or 50 year old grime will stop it from moving freely. Left to right is the proper method. Keep at it, it will come out.

And use Kroil. Best penetrating oil you can get.

Got it.

About a week with Fluid Film in there did the trick.
