I wasn't aware that a Cobra Sidewider was a mostly plastic sight.?
(If thats the sight you are reffering to.)
Perhaps they made two versions of this sight one being made up of plastic?

I like that. It's typical. A guy goes and pays a gob of money for a bow and then is looking at mostly plastic sights to put on it. Try looking at HHA OL series if you want a very rugged, all metal, bright adjustable sight.
