browning bss sight bead

[7MMGUY]

I would like to change the bead sight on my 20ga bss sporter (1978) and need to know thread dimensions.
Thanks

I have seen them with 6-48, 3-56, and also pressed in. The only way to know what you need is to remove your factory sight.

I don't know, just wanted to say, way cool gun.

One of my favorites, they should have made more.
