My friend has a TruGlo Tru Site Extreme 5-pin, and the fiber wire on the top pin just broke. I've found that I can buy colored wire on Bowhunters Superstore. The question is, can I replace that wire with the wire I've found online? The wire on the sight has a transparent, protective coating around it, and I'm not sure if I can take the fiber optic out of it and thread a new one in. Also, I'm not sure about how to get the new wire into the pin itself. And how do I terminate the end of the wire? Do I just cut the wire and burn the end with a lighter? Can anyone help me out? Thanks in advance!! -Chris
