Help! Stuck Dove Tail Sight

[Hams42]

Need some advise. I am trying to install a rear iron sight on a old 22 WMR that I'm trying to sell. I got it about 1/3 in and it has stopped. I've tried pushing it back out the other way with no luck.

Suggestions?

Update i have got it to move half way but am at an impass. Barrel won't stop rolling.

And a padded vise

Once you get it out carefully file along one of the flat surfaces without changing the angle. Go a few swipes at a time until it will drop in about 1/3 of the way, then tap it in.

Tried that. Added some more lubricant and that helped a bit. I feel like a pusher tool would be my best bet but I can't find one that would work with the rounded barrel.

Played with this task on my BP kit.
I took a triangle file and smoothed one face. With the smooth face down, file the angled notch on the barrel. Couple passes then check it...repeat.
Disclaimer: be patient.

If you can get it out, stick it in the freezer for a bit, then I bet you could tap it right in.

Elementary dear Holmes.

Oh I wish I would have thought about that at the start.

Some sights are tapered, you can measure the difference with a micrometer. I would remove it by laying it on sand bags and driving it out. Then try from the other direction.

Oh sand bag may work to keep it from rolling.

I am going to give it an hour or two get some grub in me and revisit this. I think I'm being irrational right now and need a breather.
