I'm trying to remove the front sight from a typical mil barrel. I know that the pins are tapered maybe .003 or .004 I figured that they come out to the right, looking out towards the target. I tried the usual machinist punch and hammer. No dice. So I tried in the hydraulic press but without a jig to hold everything, that didn't work. So I tried the handy-dandy bench vise (6 inch). I used a parallel machinist clamp set to just wider than the pin to support the sight and the other vise jaw to drive the pin. Once I got the setup in the vise and tightened it so I didn't have to hold on to anything, I tightened the vise as hard as I could. The pin would not move.
What am I doing wrong ? I'm NOT going to hammer on it for a nnumber of reasons.

I had a similar problem with a sight on another gun of mine (not an AR). The pin was put in the opposite way. Think perhaps they used something like Loctite?
