Review: tienen muy buena calidad - tienen muy buena luminosidad
Review: Good product, one color too dim - These seem like really and good, clear fiberoptics and I was happy overall with the product. Overall, they were flexible and strong and bright. My only complaint was the blue color was only about half of the brightness as all the rest of the colors. I installed in onto my 70 yard pin since will only be taking long shots in the day, but if I ever need it in the eve I don't know if I'll be able to count on it.

## 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.
