Henry Big Boy CCH front sight removal

[monadh]

Guys,

I am trying to change out the front sight to a Skinner, and it is not going well. I saw there was another thread where someone said "this will work" without identifying what "this" was and provided a link to Ebay, but unfortunately that link is now dead.

What can be used besides punches?

Thanks.

I continued to pound away and it came out. Sight has been replaced.
