## Questions & Answers

**Q: "Fits all bowsights and sight pins"? Really? Even when I have a sight pin that requires 0.050" fiber?**
A: This description refers to all bowsight and sight pin styles, not the size. The pin size and fiber size should match. If you have a sight pin that is 0.050" - a unique size that is not standard in the industry - you would need an 0.050" fiber.

**Q: will this fit my hi viz.  front sight on my ruger mark iv**
A: Your Hi Viz sight likely uses a much larger diameter than 0.029 which is the largest we offer on Amazon. Check with the sight manufacturer to compare sizes.

**Q: Is this long enough for Trophy Ridge React 5 pin?**
A: They're 12 inches, so they should be plenty long. I put them in my Trophy Ridge Hitman 7-pin with plenty of length to spare. Just make sure you get the right diameter.

**Q: What size will I need for Springfield xdm .40**
A: Springfield stock sights are 0.060".  Unfortunately, we do not offer this size through Amazon.

### ⭐⭐⭐⭐⭐ Nano Optics .019 Fibers
*by C***R on June 5, 2025*

I’m very happy with these fibers. They’re super bright and easy to work with. I’ll definitely use them again the next time I replace the fibers in a sight.

### ⭐⭐⭐⭐⭐ Color choice
*by J***S on September 29, 2024*

Yellow and green are the brightest for me to see.. green is by far the brightest. It appears to be 2x brighter than the yellow.

### ⭐⭐⭐⭐⭐ Super Bright!
*by V***G on March 2, 2023*

I have a bowtech SS34 with a spot hogg single pin slider. I like to work on my own gear. I wanted to change the color of my single pin...did some research and decided to go with these Nanoptics ultra super flex 12". Dang! they are bright....The original spot hogg fiber was almost 16"long and wasn't sure if this 12" would do. No worries....it works great....super bright! would recommend for sure. Colorado backcountry bowhunter.
