This is a pin i thought of using on any x-metal that uses a pressed in rivit.now this one is longer than needed for lets say a juliet but you get the idea.the domed front will fill in the holes left by the extracted rivit making the front of the nosebridge look "factory".so all you would have to do is tap the rear of the nosebridge like the XS does,and now anyone can mix and match parts i.e plasma with x-metal or gold with plasma ect. now we wouldnt do this to a collector grade of shades but a totally customizable x-metal would be unique idea......this is the kinda stuff THE X-MAN thinks about in his sleep.
