## 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.
