do fiber optic front sights lose their brightness and need replacing?

[Trigger Mike]

i know to mount a fiber optic sight that you melt the ends into the hole it fits in. once that is done do the sights lose their brightness and need replacing? if so how to you remove them, by punch ?

Here is a great tutorial on changing fiber optic rod:

A fiber optic sight is good for the life of the sight. It won't suffer from any sort of visibility loss due to time. Like the video above states, chemical damage. and damage to the sight in general, are the only things that will hurt them. Tritium sights, the ones that glow in the dark, will lose brightness over time. They have a little bit of tritium gas inside that goes through a beta decay which causes them to glow. Over time those will need to be replaced. Most makers say they are good for at least 10 years. Fiber optics are good until you want to replace them or break them. I've had a fiber optic bead on my duck gun for those early morning shoots for almost 10 years now. Just as good now as it was then. I also use a set of tritiums on my EDC. I've had those for about 8 months or so and love them.

got a used pistol and the fiber optic seems cloudy in parts when looking at it from above. it sights fine mostly but thinking a newer one might make it brighter.

I was given a 20 ga Ithaca 200E for Christmas in 1968. The fiber optic sight still works well.

The newer fiber optic sights are designed to better protect the fiber optic than they were years ago. Even if one was to break, you still have a post sight to use. Smokin Gator
