RE: broken fiber optic in cobra sidewinder sight
Just get some Fitz Fibers. You dont even have to soak them in hot water. I actually took one and tied it into a knot and it never broke . Also they are very bright. If your pin is the .019 get the tubing with the fibers. The tubing will fit right into the hole where it comes out of the sight and then goes up to the front of your pin. Just be ready to wait awhile , sometimes they take quite awhile getting to you , I waited 5 weeks to get mine but they are very good fibers.
