I can’t find a decent 1/16” roll pin punch to save my life.
I know where to find them. I want to find ones that won’t bent when you look at them.Maybe check out a good hardware store. We just got a tractor supply recently. They have saved me and my son a few times on things. They have a large area with individual fasteners.
I think you are right, I have tried four different brands and none seem to last more than one of two front sight changes.Small roll pin punches are a tough nut to keep from bending or breaking from normal use and abuse. I typically use Mayhew punches and the small diameter punches are always the first to bend or break it never fails especially my brass punches. I should buy them in bulk like I do my drill bits.
Mayhew punches.
I'm thinking one is a roll-pin or coiled spring pin, the other a split-pin or slotted spring pin.Be aware that there are two types of roll pins: slotted and spiral. I've encountered some of each type in AR-15's.

The pin punches required in each case may be different.
