Front Sight Bead Removal

[The Rattler]

I own a 1966 Wingmaster that for which I refurbished the wood. Now, I plan to Durablue the metal.

I need to remove the front sight bead, but it is proving to be difficult. I have been unable to make it move wth a pair of needle nose pliars.

Does it in fact unscrew? I've seen a specialized tool for installing front sight beads. Will that help? A Midway video suggests using heat from a hair dryer. Will that help on this old Wingmaster? Should I use a penetrating oil like Kroil?

Before I go farther I would like the more experienced input from the members here.

Thanks.

Some 870 front beads are screw-in, some are press-in.

How can you determine which one it is? If it is screwed in, should I be able to remove it without seriously damaging it?

If you have a bead with a Pedestal… i.e. 870 Express 18.5” Barrel.
How do you get the pedestal off… thinking heating but to what temperature ?

around 1000 deg F

Look at the side of the rib and see a pin, drive it out and then pull up on the bead. You’ll see a wedge cut in the bead. The drive pin holds the bead in.
