My tactical shotgun does have very tactical sights at all. Barrel is parkerized and has a small ramp with a bb on it. I've ordered an IPA sight which basically looks like an M1 or M14 front right. I need to removed the stock front sight and attach the new sight...and I want to do it without having to repark the barrel. How do I remove the old sight? I was told that the new sight needs to be silver soldered on. My jeweler-pal says he knows a guy with a laser and that's the best way. Are there alternatives? I appreciate all suggestions! thanks!!!
