Mossberg factory fiber optics?

[Isomaad]

Hey guys, I was wondering if someone could give me some info on how the factory fiber optics on a Mossberg 930 Turkey are attached?  I want to remove them so I can put on a set of Williams Universal Slugger sights with ghost ring.  Since I'm paralyzed with not much use of my hands, my buddy will actually be doing the work but I'd like to know how the factory sights are attached going into it.  Any info would be appreciated.  Thanks!

I think they just clamp on the rib. I moved mine. A small flat head screw driver should do the trick

Thanks, sounds like it shouldn't be too much trouble to remove them.
