Ok guys, I have a project right now that is essentially a trying to duplicate the FN SLP Competition shotgun. You will notice that the FN has a folding rear sight that sits below the line of sight. This lets you shoot as a shotgun normally, but flips up for slugs. I've been around shotguns my entire life, they are my strong point in shooting. I'm not looking for any suggestions there.
I called FN, and they were not willing to sell me the rear sight. Now to me, the sight looks just like the Lyman #16 folding leaf sight, which can be had for $15. I see Marbles also makes a version, but it is slightly taller. I bought the Lyman, and it is slightly too tall. FN must have a taller frame than Mossberg. What I did to fix this though, is to put the sight in the mill, and take off about .040". This put it below the line of sight, so it is possible to make this one work. I can't get the screw heads below, but I can live with that.
I'm wondering if someone has another idea though, as I see better sights from time to time, but only on old guns. A perfect example I've found is the Lyman #6 folding leaf sight for a Winchester. It doesn't have to be height adjustable, just windage adjustable, which a dovetail provides. The Lyman #6 would be perfect, you can't get any more low profile than that. Does anyone know of a source of new Lyman #6 sights or similar. Or maybe another option?
