AR15 Front Sight Removal

[setsdw]

I'm removing the standard front sight from my AR and putting on the Yankee Hill flip up. Anyone know what size punch I need to remove the taper pins?

3/32 taper punch.

I use these Brownells videos a lot when I work on my AR. Here's the one showing the removal of the front sight gas block if that's helpful.
