I've toying around with the idea of a holographic optic of some kind and realized that the front A2 sight on my Bushmaster is in the way. I'm assuming I'll need to replace the front sight with either a flattop gas block or one with a flip up iron sight.

My question is, how the hell does one go about removing the A2 front sight? It appears as though it's pinned in place, and I was just about to go grab my punches until I noticed that both ends of each pin appear to have a head of sorts on them, leading me to believe I can't drift them out. Is this true, or am I probably hallucinating?

My dad bought an air-powered demmel-like tool shortly after Christmas and has been eager to use it on something. I'm beginning to think he has the right idea.

How should I go about doing this?
