My BEO Remington trap gun has a slot milled in the barrel about 2 1/2" forward of the breech. This looks like great grandpa trap shooter was accessorizing a rear sight maybe a Lyman front sight? We trapshooters didn't start monkeying around the guns just yesterday!! I am seriously thinking about finding a sight to try.
