RE: Fiber Optics help needed!
I have no idea what would have done this to the sights; I wash the muzzleloader with mainly soap (Dawn dish liquid) and hot water, sometimes muzzleloader cleaners, in the off-season it stays inside a padded hard case. My hunting buddies all do the same thing and haven’t this problem.
{My muzzleloader is a Winchester and they mostly have Knights, if you’re interested}.
There is no name on my sights, but I think they are Durabrights by CVA.
I never use any abrasives on the gun, just cleaning brush on the inside of the barrel, but nothing else.
The fiber optics look like they have a “dull film” over them, especially the front sight, almost looks like peeling skin to be honest.
