What thread size / front bead Browning BPS

[Jollyarcher]

I'm looking to order a fiber optic replacement front bead, can anyone tell me what the proper thread size is for a front sight bead on the Browning BPS (12 gauge) shotgun? I was looking at one called the Extra Lum, by Marbles. Never heard of them, but they look interesting... have a peek, tell me whatcha think...

I haven,t had the need to take the sight off one,or replace one as of yet. Fron sight beads come in three different threads. when you order your sights they usualy will say what gun they are made for!! So when ordfereing just tell them you want one for your BPS/ The standard different threads are 6x48,3x56,8x40. The first two are the ones used the most. vangunsmith
