just bought a hi-viz spark II front sight for my pardner protector. my question is; what size are the threads on the factory bead? the kit came with 5 different adapters: 6-48,5-40,3-56,3mmx.5,3mmx.6. will any of these fit my gun? it is not a vent rib just a bead.
also, what is the best way of removing the old front bead. i'm not concerned about damaging the old bead but do not want to strip the threads. thanks
