I've recently acquired an older family Krag that's been cut down, and I'd like to replace the front sight back to something original at least in looks.  But first I need to remove the old one in the attached picture.

This is a cut down sporterized one, so I'm fairly confident there's no dovetailing, etc. and it looks to have solder on the base so I assume just soldered on.

I've looked at a few references to just cooking the thing off with a torch, which looks pretty straight forward.  However I don't have a hot one to really get it red, just propane.

If it is silver solder and takes more heat to get it off, would it be unreasonable to actually grind down most of the metal mass of the sight, so that the propane torch could maybe get more heat to the remaining metal?  Does that make sense at all?
