I just tried installing mine, and I could not get the stock bead off, so I swapped front sights with another gun that did have a tapped front bead, so I now have 2 mixed sets of sights if that makes sense. The front sight for this TruBead will fit over the stock bead, but it was not as tight as I would have liked it to be. I may try tapping the stock bead hole or drilling and tapping a new hole if I cannot get the swapped front sights to work. Let me know if you figure out an easier way.
