    Depending on the age, it could be any one of the three.

    If it is a metal front bead, it should either be pinned or swaged in place. If it is old enough to be pinned, you can look at the side of the rib just below the bead and see the end of the pin. Drift it out and you can pull the bead out of the rib. If it was made in 1990, it should be swaged in place. The best way to remove the swaged version is to put the barrel in the vise on a milling machine,mill a flat on top of the bead, use a dial indicator to find the center of the bead and drill with a #2 center drill until the bead comes off. If you want to replace it with a Bradley style front sight, drill about .150 deep with a #45 drill and tap with a 3-56 bottom tap.

    If it's one with the side pin make real sure you support the rib very well before you start driving that pin out. Sometimes that side pin is hard to see.

    The crimped in sights can be pulled out. I use a small punch and tap all the way around the bead to push the crimp back. The bead will now be loose enough to pull out. You'll need to tug a little bit.

    Once its been removed, you can just use a 6-48 tap to thread the existing hole. Most bead styles can be had with the 6-48 thread.
