Has anyone configured a USH barrel with rifle sites? Anyone have one configured with both R/S and a Scope? From what all of you that own these USH 20ga's have written, these seem to be nearly the ultimate slug guns. I think I would like to have one, but as most of you know already, I would have to have open sights installed in order to have them on this barrel. Therefore, my question. Any thoughts or comments on this would be appreciated.
