I'd like to swap my bead site for a tru glo site on my Beretta 686 Onyx 12GA. Pretty sure the bead unscrews, my question is how do I remove the bead site without damaging it? I'm sure a long nose vise grips will do the trick but it would also damage the bead removing it.

Is this something best left to a gunsmith?

Any advise would be appreciated
