Benelli M2 tactical front sight fiber optic options?

[EvolutionGSR]

I've only found one, at this link here:

I'm looking for more of a straight type fiber optic sight that can be screwed into the front sight of the ghost ring set that comes on a Benelli M2 tactical. Anyone know of any that will work with no modifications?
