I seen a custom built muzzle loader that had a square notch rear sight and a front sight that had a flat top. You line up the top of the flat front sight with the top of the notch in the rear sight. Does anyone know what these sights are called or where to buy them ?
TC's tang mounted peep sight will work on a New Englander, using the original front sight...but if you are wanting to change out to regular replacement sights, there are lots of options available.
