Hi again folks. I want to swap the front blade (and rear) to something like a Williams Fire Sight set.

The problem is, the only attempts I've seen to remove the front sight blade have been to support the ramp with a dowel or something similar and then to hit the blade with a hammer and punch. This has in some cases resulted in breaking off or stripping out the ramp base screw. But in my case, I want to keep it.

Is there an actual tool or can anyone help me get creative to come up with something that might work like a pusher tool? It may be possible to fabricate something...
