MECCANIXITY Fiber Optic Rods PMMA 1mmx20cm for Sight Filament Red, Green, Orange 1 Set Pack of 5

It’s like a Hi Vis product for firearms Reflects light excellently

Fit perfectly into the OEM front sight of my CZ S2. Original fiber got lost during competition. Before installing into the front sight, I cut the fiber slightly longer than the length required. I held a lighter flame close enough to "mushroom" one end of the fiber. I then installed into place, with the "non-mushroomed" end at the muzzle. With a bit of the fiber rod extending out the front of the sight, I held a lighter flame close enough to "mushroom" the front end. This makes both ends of the now installed fiber rod a bit thicker than the hole in the front sight that the fiber slides into. This secures the newly installed fiber rod into the sight. Tested and it looks like the new fiber rod captures light well. The red may be a little like pinkish red, but it works fine and the price is certainly right. Glad I purchased these. I may experiment with new colors in the front sight as I have PLENTY of fiber to experiment with.

Exactly as described , fixed the front sight of a “ SX4” very easily . Passed it through the hole , clipped it with nail clipper and heated both ends with a lighter . Done

It worked well for what I needed. It fit a great, maybe just a hair loose but I put a slight bend on it to keep it from moving at all. Brightness is what was expected, and it’s nice to have some color options available. I have a lifetime supply of fiber now considering I used less than an inch of it lol.

I needed to replace the fiber optics on my bow, and my local store wanted 3x the price of these, and there was less of them in the pack. I got these and reinstalled them myself.
