Pat-
Here's the front sight on my Shiloh. The base is an original Shiloh, with the penny piece replacing the factory steel blade.

I like it very much. When there's any kind of light from behind with the shooter in position, the top of the blade glows about like a fiber optic.

I prefer the copper color to silver. One of my muzzleloaders had a very elegant sterling silver front sight that worked great in a green forest or grassland. But, in a winter ML match it became completely invisible against a snowy background and a white target. Because snow is not an unusual feature of the landscape in Michigan's Upper Peninsula, I switched it out for a bright copper front sight. I whittled it out of an Australian two-cent piece which is a somewhat wider than a US penny.

Based on extensive experience, the gunwriters of the 30s and 40s wrote glowing praises of the Redfield Sourdough front sight base with its brass face.

PM incoming.
