OK, so my set of Trijicon sights for my AR-15 came in today but the rear sight won't fit on my folding Troy BUIS. After taking my rear sight apart and losing the ball bearing twice I discovered the Troy apparently has a larger windage screw than standard. So before I send these back to Trijicon for a refund I thought I would offer them to someone here locally.

They are $85 at Trijicon but can be found cheaper around the net. I'll take $70 cash and will meet you around Baton Rouge or come by my office at the Bonne Carre business center. They are still in the package and come with a sight tool as well.
They should fit on any standard M16 or AR sights. I don't know why the rear won't fit on mine but I'll be happy if someone can educate me why they won't work. I really wanted tritium sights but I also really want Troy BUIS.
